RAR is one of the few archive formats you can receive but not always create on Android, since the format's compression algorithm is licensed. That's fine for everyday use — almost every archive tool on the Play Store, including ZArchiver, can open a RAR file even though it will save new archives you create as ZIP or 7Z instead.

Before you start

Make sure the archive has finished downloading completely. A RAR file that stops partway through a download will fail to extract, and the resulting error message rarely mentions that the file is simply incomplete. Checking the file size against what the source page lists is the fastest way to rule this out.

Extracting a single RAR file

  1. Open your archive manager and browse to the folder containing the .rar file — usually the Downloads folder unless you changed the save location in your browser.
  2. Tap the file once. Most archive apps show a preview of the contents before asking what to do with them.
  3. Choose "Extract Here" to unpack into the current folder, or "Extract to" if you want to pick a different destination, such as a dedicated folder per download.
  4. Wait for the progress indicator to finish. Large archives with many small files typically take longer than a single large file of the same total size, since each file has to be written separately.
Tip: if you only need one file out of a large RAR archive, look for a "view contents" or folder-icon option before extracting. Most tools let you tap into the archive like a regular folder and pull out individual files without unpacking everything.

Extracting multi-part RAR archives (.part1.rar, .part2.rar...)

Large files are sometimes split across several .rar parts to make uploading or sharing easier. You do not need to extract each part separately. Keep every part in the same folder, then open only the file named part1.rar (or the part with the lowest number). The archive tool reads the remaining parts automatically as long as they sit alongside the first one and keep their original filenames.

If a part is missing or was renamed, extraction will stop with an error partway through, since the tool has no way to reconstruct the missing segment of data.

RAR5 archives specifically

RAR5 is a newer variant of the format with a different compression scheme than classic RAR. Archive apps that haven't been updated in a few years sometimes can't read it, which shows up as a "not a valid archive" or "unsupported format" error even though the file itself is fine. Updating your archive app to its current version from the Play Store resolves this in almost every case.

What to do if extraction fails

  • "CRC failed" or "data error" — the file is corrupted, usually from an interrupted download. Re-download it rather than retrying the extraction.
  • "Wrong password" — the archive is encrypted. Double-check the password source; passwords in shared links are often case-sensitive.
  • Extraction stops with no message — you may be out of storage space. Free up room and try again, since RAR files can expand significantly once decompressed.
