End-of-central-directory signature not found

"End-of-central-directory signature not found" means the ZIP's final archive index is missing or unreadable. FileFix scans surviving local records, writes a fresh directory, and shows the recovered file list before checkout. A one-time $5 — 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.

Unrepaired files are kept encrypted for up to 30 days, then deleted.

FileFix can't fix that kind of file yet.

Why this happens

ZIP readers normally locate the end-of-central-directory record near the archive tail and use it to find the central directory. A truncated download or copy can remove both while leaving earlier local file records intact.

The record is easy to picture: it is the last thing a ZIP writer puts at the end of the archive, a short block whose signature every reader searches for first. Because it sits at the very end, it is the first casualty of a truncated download, an interrupted copy, or a transfer that silently stopped early — the beginning of the file can be perfectly healthy while the closing record never arrived.

You can rule out the simple causes quickly: re-download the file, compare its size with the source's where shown, and try a second extractor. When every copy and every tool reports the same missing signature, the tail is genuinely gone from your copy of the file.

The missing signature is an index failure, not proof that every compressed member is gone. Members whose local headers and streams survived can be scanned without the old directory.

FileFix decompresses readable stored and DEFLATE members under safety limits and writes them into a new ZIP with a fresh central directory. The summary lists only the entries recovered from the upload.

What we can and can't recover

We can usually fix

  • Archives that show "unexpected end of archive"
  • Archives cut off during a download or copy
  • ZIP files with a damaged central directory
  • Archives that show the right size but won't open

We can't fix

  • Encrypted archives
  • Multi-part or split archives missing their other parts
  • Genuinely empty (0-byte) files
  • Files on physically damaged drives (that's hardware data recovery)
