| OS | Recommended CLI tool | GUI alternatives | |----|----------------------|------------------| | Windows | unrar (official) or 7z (7‑Zip) | 7‑Zip, WinRAR | | Linux | unrar (non‑free) or unrar-free (limited) or p7zip (7z) | Archive Manager (file‑roller) | | macOS | unarchiver (homebrew: brew install unrar) or 7z (brew install p7zip) | The Unarchiver, Keka |

Why both?
unrar can handle solid archives and RAR5, while 7z is often already installed on many systems and works well for most RAR 4 archives.

| Symptom | Likely cause | Fix | |---------|--------------|-----| | CRC error or Corrupt archive | One or more volumes are damaged. | Re‑download the offending part. | | Cannot find volume 2 | Missing part or wrong filename. | Ensure naming pattern is exactly ...partN.rar. | | unrar: command not found | Tool not installed or not in $PATH. | Re‑run the installation commands above. | | Extraction stalls, 100 % CPU but no progress | Very large solid archive with limited RAM. | Add swap or extract on a machine with more RAM. | | top shows no CPU usage | Extraction finished (or you typed top in the same window). | Run top in a different terminal while extraction is running. |

ls -1 fc2ppv4536489part*.rar
# Expected output (example):
# fc2ppv4536489part1.rar
# fc2ppv4536489part2.rar
# fc2ppv4536489part3.rar
# ...

If any part is missing, you’ll get an error like:

ERROR: Missing volume 3 of the archive

Solution: Re‑download the missing volume(s) before proceeding.

find ./extracted_folder -type f | wc -l   # count files
find ./extracted_folder -type f | less    # browse list

Goal: Extract the multi‑part RAR archive fc2ppv4536489part2.rar (and its companion parts) on Windows / Linux / macOS, then use the top utility to watch the extraction’s CPU/IO usage.
