Old .doc won't open in new Word
An old .doc file that will not open in a new version of Word may simply use the legacy binary format, but a corrupt file is a different case. FileFix repairs the modern .docx format, not the legacy .doc binary — so save or convert the document to .docx first, in Word or any editor that can still read it. If the converted .docx is damaged or still will not open, upload that .docx for a repair attempt and see the recovered text summary first. A one-time $14 — and only if the repair works.

Good news — your file isn't damaged. No charge.
There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.
We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge. You can try another file.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, and document files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, ZIP, and PDF). We're adding support for more formats over time.

Why this happens
The .doc and .docx extensions identify different formats: .doc is Word's legacy binary document format, while .docx is a ZIP package containing XML parts. A newer Word version can normally open a valid .doc, so changing the extension does not convert or repair the file.
When other valid .doc files open but this one does not, the legacy document's container or internal records may be damaged. That corruption case is distinct from a format-compatibility problem and requires recovering readable content rather than renaming the file.
FileFix works on the .docx package, not the legacy .doc binary, so there is no .doc upload path today. When a converted or exported .docx will not open, FileFix scans the surviving package parts and rebuilds recoverable body text into a minimal .docx; the summary reports paragraph and word counts plus a redacted excerpt, and formatting or content that never survived conversion is not promised. If no program can read the original .doc at all, there is nothing to convert and this repair cannot help.
What we can and can't recover
We can usually fix
- Documents that show "Word found unreadable content"
- Documents Word refuses to open
- Documents cut off mid-save or mid-transfer
- Files that show the right size but won't open
We can't fix
- Password-protected/encrypted documents
- Genuinely empty (0-byte) files
- Deleted or formatted files (that's data recovery, a different job)
- The old binary .doc format (this repair is for .docx)

Questions
Most often the main document body XML or the package relationships. Text can survive in the body even when those wrappers are damaged, which is what the rebuild targets.
Yes, on a duplicate of the file. Save any recovered result under a new name; if Word still refuses it or the text you need is missing, upload the untouched copy for a separate rebuild.
The rebuild prioritizes readable body text over formatting. Styles, images, and headers are not promised, so use the excerpt and counts to evaluate text recovery specifically.
