How to fix "Unexpected end of archive" in Windows Explorer, WinZip, 7-Zip
Unexpected end of archive
What this error means
The archive is shorter than it should be: the index at the end is missing.
Why it happens
- Download stopped early
- Copy interrupted
- Disk full while creating the archive
How to fix it
- Download the file again if you can
- Try 7-Zip: right-click › 7-Zip › Open archive — it lists files it can still see
- Upload it here to rebuild the archive from every file that survived
About ZIP archive files
A ZIP archive stores each file with its own small header, then a central directory (the index) at the very end. If the end of the file is missing, tools say the archive is invalid — but every file before the cut can still be read.
