Error messages and their fixes
| Error text | What it means | Fix |
|---|---|---|
| CRC failed / checksum error | The extracted data doesn't match the checksum stored in the archive — corruption or an incomplete download | Re-download the file; if that doesn't help, try repairing the archive |
| Unexpected end of archive | The file is truncated — it ends before the archive structure says it should | Re-download the archive; if multi-part, confirm every volume is present, per multi-part RAR files |
| Cannot create file / cannot create folder | WinRAR can't write to the destination — permissions, a locked file, or a path issue | Extract to a different folder you have full write access to, such as your Documents folder |
| Access is denied | The destination folder or an existing file there is read-only or in use by another program | Close programs using that folder, check folder permissions, or extract elsewhere |
| Not enough disk space | The extracted, uncompressed contents won't fit on the destination drive | Free up space or extract to a drive with more room; check the archive's uncompressed size first |
| The specified path is too long | Windows has a path-length limit that deeply nested extracted folders can exceed | Extract closer to the drive root, e.g. C:\extract\, to shorten the resulting path |
| Cannot open [file]: no such archive | WinRAR doesn't recognize the file as a valid archive — wrong extension, or not actually an archive | Confirm the file extension and use the archive inspector to verify the file type |
General steps when an error isn't listed above
- 1Read the exact wordingWinRAR error text is usually specific about which file and which operation failed — note it exactly before searching further.
- 2Test the archive firstRun Tools > Test archive to isolate whether the problem is the archive itself or the extraction destination.
- 3Try a different destination folderMany errors — permissions, path length, disk space — disappear when you extract somewhere simpler, like a fresh folder near the drive root.
- 4Confirm the software is currentAn outdated extractor can occasionally mishandle newer archive features. Reinstalling from the official WinRAR download (external) resolves this.

Frequently asked questions
What does "unexpected end of archive" mean?
It means the file is shorter than the archive's own structure expects — almost always an incomplete download or a missing volume in a multi-part set.
How do I fix "access is denied" during extraction?
Close any program that might have a file open in the destination folder, check that you have write permission there, or extract to a different folder such as your Documents directory.
Why does extraction fail with a path-too-long error?
Windows limits the length of a full file path. Extracting to a shorter path, like a folder near your drive's root, usually resolves it.
Is a CRC error the same as a corrupted archive?
It's a symptom of it — the extracted data doesn't match its stored checksum. The cause is often an incomplete download rather than true file damage; see [corrupted RAR file](/corrupted-rar-file).
