Troubleshooting
RAR Archive Has Missing Volume: What to Check
A missing-volume error means the extractor found a gap in a sequence of RAR parts it expected to be complete — one or more `.rar` or `.partNN.rar` files simply aren't in the folder.
Multi-part RAR archives split one logical archive across several numbered files, such as archive.part1.rar, archive.part2.rar, archive.part3.rar. Every part is required; extraction reads them in sequence and stops the moment it can't find the next number in the sequence.
Steps to check
- 1List all files with the matching base nameSort the folder by name and confirm every part from
part1through the highest number is present, with no gaps in the sequence. - 2Check the numbering format matchesOlder RAR naming used
.rar,.r00,.r01, etc., while newer naming uses.part1.rar,.part2.rar. Mixing files from two different splits of the same content (e.g. downloaded from two different sources) will look complete by file count but fail because the internal structure doesn't match. - 3Re-download only the missing part(s)If you can identify exactly which numbered file is absent, you often only need to re-fetch that one file rather than the entire set.
- 4Check for recovery volumes (.rev files)Some multi-volume sets include
.revrecovery volumes generated by WinRAR's protect feature. If enough.revfiles are present, WinRAR can reconstruct a missing.rarpart without needing the original. - 5Attempt partial recovery if a part is unrecoverableIf a middle volume is permanently missing and no recovery volumes exist, you can sometimes still recover the files that were fully contained in the earlier volumes using 'Keep broken files', though anything split across the missing volume will be lost.
Frequently asked questions
Do I need every single part to extract anything?
Yes, for standard multi-part extraction. Recovery volumes (.rev) are the only mechanism that can substitute for a genuinely missing part.
How do I tell which part is missing?
Sort the folder alphabetically/numerically and look for a gap in the sequential numbers between the first and last part present.
What are .rev files exactly?
Recovery volumes created by WinRAR's 'protect archive' feature, which can reconstruct one or more missing or damaged .rar volumes using redundant data, similar in concept to a recovery record on a single archive.
Can I extract just the files that were in the volumes I do have?
Sometimes, using 'Keep broken files', but only for files that don't span into the missing volume; files split across it will be incomplete.
