Data Recovery by File Type: Recover Documents, Photos, Videos, Audio, Archives & Email Files
When you lose files, knowing what you lost is as important as knowing where you lost it from. Different file types — Word documents, JPEG photos, MP4 videos, ZIP archives, Outlook PST email files — have different internal structures. Professional data recovery software uses file signature recognition to identify and reconstruct each file type based on its unique internal pattern, not just its file name or extension.
XRecovery supports 1,000+ file formats across 6 major categories. Whether you need to recover a critical Excel spreadsheet for work, restore family photos from a formatted SD card, retrieve 4K video footage from a corrupted camera, or recover your entire Outlook mailbox — this guide explains exactly which file types are supported and how recovery works for each category.

FF D8 FF, a PDF with %PDF, and a ZIP with PK. When the file system is damaged or files have been deleted, recovery software reads the raw data on your drive and matches these signatures to identify and reconstruct files — even without file names or folder paths. This is why XRecovery can recover files that other tools miss.
Documents
Document files — Word, Excel, PowerPoint, and PDF — are the most commonly recovered file category. Whether you're a student who lost a term paper, a professional who accidentally deleted a critical spreadsheet, or someone who formatted a drive containing years of work documents, document recovery has the highest success rate of any file type because these formats have well-defined internal structures that recovery software can reliably identify.
Supported Document Formats

Document-Specific Recovery Tips
- Unsaved documents: Microsoft Office applications save temporary copies (AutoRecover files) every few minutes. These are stored in
C:\Users\[Name]\AppData\Roaming\Microsoft\[App]\and often have .asd, .tmp, or ~$ prefixes. Recovery software can retrieve these temp files even if you never saved the document. - Modern DOCX/XLSX/PPTX formats: These are actually ZIP archives containing XML files internally. If a DOCX file is partially corrupted, you can sometimes rename it to .zip, extract the XML content, and recover the text. XRecovery handles this automatically.
- PDF recovery: PDF files have a distinct header (
%PDF-) and trailer (%%EOF), making them highly recoverable even from deeply corrupted drives.

Photos & Images
Photo recovery is one of the most emotionally significant data recovery tasks — these aren't just files, they're memories. XRecovery supports all common image formats including everyday formats like JPEG and PNG, professional formats like PSD and TIFF, and — crucially — camera RAW formats from every major camera manufacturer.
Everyday Image Formats
Camera RAW Formats — By Manufacturer
| Camera Brand | RAW Format(s) | Example Cameras |

| GoPro | GPR (RAW) | HERO13 Black, HERO12 Black |
| Universal RAW | DNG | Adobe Digital Negative — supported by many cameras and phones |
Additional Supported Image Types
Photo-Specific Recovery Tips
- RAW files are large: A single RAW file can be 30–100 MB. On high-capacity cards (256 GB+), deep scans may take several hours. Be patient — the preview feature lets you verify files in real-time as they're found.
- JPEG fragmentation: JPEG files that are partially overwritten may display visual artifacts (gray blocks, color banding). If a recovered JPEG looks incomplete, try a deeper scan — the remaining fragments may be on a different part of the drive.
- SD card photo recovery: For photos deleted from camera memory cards, stop using the card immediately. Every new photo taken permanently overwrites recoverable data. See our complete SD card recovery strategy guide.
- HEIC/HEIF from iPhones: If you transferred iPhone photos to a Windows PC, they may be in HEIC format. XRecovery fully supports HEIC recovery.

Videos
Video files are among the most challenging file types to recover because they're typically large (often gigabytes in size) and frequently stored in fragmented form across the storage device. When a video spans multiple non-contiguous clusters, a quick scan may only recover part of the file, resulting in an unplayable video. XRecovery's Deep Scan engine includes specialized video reconstruction logic to locate and reassemble fragmented video files.
Supported Video Formats
Video Recovery by Source
| Video Source | Common Formats | Recovery Notes |
|---|---|---|
| Smartphone | MP4, MOV, 3GP | Generally well-recovered; most phones avoid heavy fragmentation |
| DSLR / Mirrorless Camera | MOV, MP4, AVCHD (MTS), MXF | High-bitrate video often fragmented; use Deep Scan |
| GoPro / Action Camera | MP4 (chaptered) | GoPro splits long videos into chapters; recover all segments for complete footage |
| Drone (DJI) | MP4, MOV, DNG (RAW) | High-resolution 4K/8K files very large; recover to a drive with sufficient space |
| Screen Recording | MP4, AVI, FLV | Variable-bitrate recordings more prone to fragmentation |
| DVD / Blu-ray | VOB, M2TS, IFO | Multiple-file structure; recover all related files for complete playback |
Video-Specific Recovery Tips
- Fragmented video: If a recovered MP4 or MOV file won't play, it's almost certainly fragmented. Run a Deep Scan specifically targeting video signatures. XRecovery's video reconstruction algorithm can often rebuild fragmented files by locating and joining scattered data clusters.
- GoPro chaptered files: GoPro cameras split long recordings into ~4 GB or ~12-minute chapters (e.g., GOPR0001.MP4, GP010001.MP4). If you lose a chapter, recover all adjacent chapters — they form a continuous recording and you'll need them all.
- 4K/8K video files: Ensure your recovery destination drive has at least twice the free space of the largest video file you're trying to recover. High-resolution video files are enormous.
- Corrupted video repair: If recovery produces a file that won't play at all, some tools can repair damaged video containers (MOOV atom repair for MP4, index repair for AVI). XRecovery's Deep Scan attempts this reconstruction automatically.
Audio
Audio files range from compressed formats like MP3 and AAC (used by music players and streaming services) to lossless formats like FLAC and ALAC (used by audiophiles and audio professionals) to uncompressed formats like WAV and AIFF (used in professional recording and editing). XRecovery supports all of them, plus specialized formats from music production software and portable recorders.
Supported Audio Formats
Audio Format Comparison
| Category | Formats | Typical Size | Common Source |
|---|---|---|---|
| Compressed (Lossy) | MP3, AAC, WMA, OGG, AMR, RA | 3–10 MB per song | Music libraries, voice memos, podcasts |
| Compressed (Lossless) | FLAC, ALAC, APE, WV, OPUS | 15–40 MB per song | Audiophile collections, archiving |
| Uncompressed | WAV, AIFF, PCM, AU, SND, CAF | 30–80 MB per song | Studio recordings, editing projects |
| Multi-Channel / Surround | AC3, DTS, A52, MKA | Variable | DVD/Blu-ray audio, home theater |
| MIDI / Sequencer | MID, MIDI | < 1 MB | Digital instruments, DAW projects |
Audio Recovery Tips
- Voice memos and recordings: These are often stored as M4A (iPhone), AMR (Android), or WAV (dedicated recorders). Check the specific folder these apps use — most save to a dedicated app folder rather than the general Music directory.
- iTunes / Apple Music libraries: iTunes uses M4A (purchased/imported) and M4P (protected). XRecovery can recover both, but DRM-protected M4P files may only play on authorized devices.
- DAW project files: If you use FL Studio, Ableton, Logic, Cubase, or Pro Tools, look for project files (.flp, .als, .logicx, .cpr, .ptx) in addition to audio samples (.wav, .aif). Recovering the project file is essential to preserve your arrangement and edits.
Archives & Compressed Files
Archive files present a unique recovery challenge: they're containers within containers. A single ZIP or RAR file can hold hundreds of individual files inside it. If the archive file itself is deleted, you need to recover the container first, then extract its contents. If the archive is corrupted after recovery, specialized repair tools may be needed to salvage the files inside.
Supported Archive Formats
Archive Types by Use Case
| Archive Type | Formats | Typical Use |
|---|---|---|
| General Compression | ZIP, RAR, 7Z, GZ, BZ2, XZ | File sharing, backup compression, email attachments |
| Disk Images | ISO, DMG, IMG, NRG | Software distribution, optical disc backups, macOS installers |
| Software Packages | MSI, CAB, RPM, DEB, PKG, JAR, WAR, EAR | Windows installers, Linux packages, Java applications |
| Tape / Unix Archives | TAR (combined with GZ/BZ2/XZ) | Unix/Linux system backups and file collections |
Archive Recovery Tips
- ZIP is the most recoverable archive format: The ZIP format stores a central directory at the end of the file. Even if the beginning of a ZIP file is partially overwritten, recovery tools can often rebuild the archive from the central directory. XRecovery's ZIP signature detection recognizes both the local header (
PK\x03\x04) and the central directory (PK\x01\x02). - RAR recovery parity: If your RAR archive was created with recovery records enabled, WinRAR can repair minor corruption. Always enable recovery records when creating important RAR archives.
- Recovering files from inside an archive: If only the archive itself is damaged but the drive is otherwise intact, recovery software can sometimes find the individual files that were inside the archive scattered across the drive — but this requires Deep Scan and the original files were extracted at some point.

Email & Other Files
This category covers email data files, eBooks, 3D models, database files, system logs, and other specialized formats that don't fit neatly into the previous five categories. Some of these — particularly Outlook PST/OST files and email message files — are among the most critical files users need to recover, as they often contain years of business correspondence and irreplaceable communication history.

Email Recovery — PST & OST Deep Dive
Outlook PST (Personal Storage Table) and OST (Offline Storage Table) files are the most critical email recovery targets. A single PST file can contain years of emails, contacts, calendars, tasks, and notes — making it one of the most valuable files on a user's computer.
| File | Used By | Typical Location | Max Size |
|---|---|---|---|
| PST | Outlook (POP3, IMAP archives, local folders) | C:\Users\[User]\Documents\Outlook Files\ |
50 GB (Outlook 2010+) |
| OST | Outlook (Exchange, Office 365 cached mode) | C:\Users\[User]\AppData\Local\Microsoft\Outlook\ |
50 GB (configurable) |
| MSG | Individual saved email messages | Anywhere the user saved them | N/A (single message) |
| EML / EMLX | Windows Mail, Thunderbird, Apple Mail | App-specific profile folders | N/A (single message) |
C:\Program Files\Microsoft Office\root\OfficeXX\ and can repair minor to moderate PST corruption. Always run it on a copy of the recovered PST, not the original recovered file.
Recovery Tips for Other File Types
- Database files (MDB, ACCDB, SQLITE, DB): These are complex structured files. If recovered but corrupted, try the database application's built-in compact/repair function (e.g., Access: Compact and Repair Database).
- eBooks (EPUB, MOBI, AZW): EPUB files are actually ZIP archives containing HTML/CSS. If recovered but won't open, try renaming to .zip to inspect and extract the content.
- 3D/CAD files (STL, OBJ, DWG, STEP): These have well-defined binary structures. XRecovery's Deep Scan recognizes their unique headers and can reliably recover them even after formatting.
- Log files (LOG, TXT, CSV): Plain text files are trivially recoverable — they have no internal structure to corrupt. The only risk is overwriting.
How File-Type-Based Recovery Works
Understanding how recovery software identifies files by type helps you make better recovery decisions. Here's the technical process:
1. File Signature Recognition (Magic Numbers)
Every file format has a unique magic number — the first few bytes that identify the file type regardless of its name or extension. Recovery software scans the raw data on your drive for these signatures.
| File Type | Extension | Magic Number (Hex) | ASCII Equivalent |
|---|---|---|---|
| PDF Document | 25 50 44 46 | ||
| ZIP Archive | .zip | 50 4B 03 04 | PK.. |
| JPEG Image | .jpg | FF D8 FF E0 | ÿØÿà |
| PNG Image | .png | 89 50 4E 47 | ‰PNG |
| MP4 Video | .mp4 | 00 00 00 18 66 74 79 70 | ....ftyp |
| WAV Audio | .wav | 52 49 46 46 | RIFF |
| RAR Archive | .rar | 52 61 72 21 1A 07 00 | Rar!... |
| Outlook PST | .pst | 21 42 44 4E | !BDN |
2. Quick Scan vs. Deep Scan
| Scan Mode | How It Works | Best For | File Names Preserved? |
|---|---|---|---|
| Quick Scan | Reads the file system's Master File Table (NTFS) or File Allocation Table (FAT32/exFAT) to find recently deleted files | Recently deleted files, Recycle Bin recovery | Yes — original names and folders |
| Deep Scan | Scans every sector of the drive looking for file signatures, then reconstructs files from raw data | Formatted drives, corrupted partitions, long-deleted files, fragmented videos | Partial — may use generic names |
3. Why File Names May Be Lost
When the file system metadata is damaged or overwritten, the Deep Scan finds files by their data signatures, not by directory entries. This means recovered files may appear with generic names like file001.jpg or recovered_video_023.mp4 — but the actual file content (photos, documents, emails) is fully intact. Always preview recovered files before saving to confirm they contain your data.

Download XRecovery FreeFrequently Asked Questions
Can I recover a deleted Word document or Excel spreadsheet?
Yes. Microsoft Office documents (DOCX, XLSX, PPTX, PDF, etc.) are among the most recoverable file types. When deleted, only the file reference is removed from the file system while the actual document data remains on disk until overwritten. Use XRecovery immediately to scan and restore Office documents with their original content intact. See our 5-method recovery guide for step-by-step instructions.
Can data recovery software recover RAW camera files (CR2, NEF, ARW)?
Yes. XRecovery uses file signature recognition to identify and recover RAW camera formats including Canon CR2/CR3, Nikon NEF, Sony ARW, Fujifilm RAF, Olympus ORF, Panasonic RW2, Pentax PEF, and Adobe DNG. The software scans the storage device at the sector level and reconstructs RAW images based on their unique file headers. Learn more about camera file recovery.
Why do some recovered video files (MP4, MOV) not play after recovery?
Video files that won't play are typically fragmented — stored in multiple non-contiguous clusters. Quick scans often fail to reconstruct fragmented videos correctly. Use Deep Scan with video-specific recovery to locate all fragments and rebuild complete, playable files. See our video recovery guide for detailed help with corrupted video files.
Can I recover corrupted ZIP or RAR archive files?
Yes. If the archive file is intact but deleted, recovery software can restore it like any other file. If the archive is corrupted, XRecovery may find the original version or recover the individual files that were inside. XRecovery recognizes all major archive signatures including ZIP, RAR, 7Z, TAR, GZ, and ISO.
How do I recover Outlook PST or OST email files?
Outlook PST/OST files store emails, contacts, calendars, and tasks. XRecovery can locate deleted or lost PST/OST files by their unique signature (!BDN). After recovery, if Outlook reports corruption, use Microsoft's SCANPST.EXE to repair minor issues. Always test the repaired file before re-importing into Outlook. Get tips for maximum recovery success.
What happens if my file type is not on the supported formats list?
Most recovery software uses file signature recognition to identify files. If your format isn't listed, it may still be recoverable if the software detects the file's unique header pattern during a Deep Scan. Uncommon formats may appear with generic names but the content is typically intact. XRecovery's Deep Scan detects far more formats than the published list — the list shows the most commonly verified formats.
Can recovered files retain their original names and folder structure?
It depends on the scan mode. Quick Scan uses existing file system metadata and preserves original names and folders. Deep Scan works by signature detection and may not recover original names — files may appear as file001.jpg, doc_045.docx, etc. But the file content is fully intact either way. Always preview before saving.
Does XRecovery support all 1,000+ file types in the free version?
Yes. The free version of XRecovery allows you to scan any device and preview all recoverable files across all supported formats — including RAW camera files, Outlook PSTs, CAD files, and archives. This lets you verify recovery before upgrading. Compare XRecovery features with other tools.
