There are some data after the end of the payload data
7-Zip's warning "There are some data after the end of the payload data" means bytes remain after a compressed member's payload. FileFix can trim trailing junk while rebuilding readable members into a fresh ZIP and show the recovered file list before checkout. A one-time $5 — and only if the repair works.

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

Why this happens
7-Zip reports this warning when a compressed stream reaches its defined end before all bytes assigned to that payload have been consumed. Those extra bytes can be trailing junk introduced by a damaged transfer, concatenation, or inconsistent size metadata.
The warning does not by itself mean that the decoded member data is missing. When the payload ends cleanly, the bytes after that boundary can be excluded while readable archive records and member streams are preserved.
You can check the impact yourself: extract the archive and look at the result. If every file extracts and opens, the warning was describing stray trailing bytes and nothing more. If extraction stops partway, reports broken files, or 7-Zip shows this warning together with "Headers Error" or a CRC message, the archive has real structural damage alongside the trailing data.
Where the trailing bytes came from matters less than what sits in front of them: a download that got an extra chunk appended, two files joined by a transfer tool, or size metadata that disagrees with the actual stream. In every case the useful move is the same — keep the members that read cleanly, drop the bytes outside the valid payload, and write a consistent archive around what survived.
FileFix scans local headers, decompresses readable stored and DEFLATE members under safety limits, trims bytes outside valid payload boundaries, and writes a new ZIP with consistent records. The free summary lists the rebuilt entries.
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)

Questions
If every file extracts correctly, the warning may only describe trailing bytes and no repair is needed. Repair matters when extraction fails or members are unreadable; the free file list shows what a rebuilt archive would contain before you pay.
A ZIP member's compressed stream declares where it ends. 7-Zip consumed the stream, reached that end point, and found extra bytes past it that don't belong to any member. The warning reports those extra bytes — it is not by itself proof that the member data is damaged.
Yes. The rebuild only carries over members that can be read, written into a fresh ZIP with consistent records. Bytes outside a valid payload boundary are not copied in, so the warning does not follow the rebuilt archive.
Trailing data on its own is a warning, not damage. When it appears alongside header or checksum errors, the archive's structure disagrees with itself in more than one place — usually the sign of an interrupted or altered transfer — and extraction results, not the warnings, tell you what is actually recoverable.
