.arj files are compressed archives created by ARJ Software. To open them efficiently, follow this concise guide:
Required Software
Install a compatible decompression tool. Modern options include:
- PeaZip (Windows/Linux)
- The Unarchiver (macOS)
- 7-Zip (Windows)
- ARJ program itself (command-line)
Step-by-Step Extraction
Step 1: Right-click the .arj file. Select your installed tool's context menu option (e.g., "Extract Here" in PeaZip).
Step 2: If using command-line ARJ:
arj x * - extracts preserving directory structure.
arj e * - extracts files to current folder.
Step 3: Authenticate if the archive is password-protected. Enter credentials when prompted.
Troubleshooting Tips
Corrupted archives: Verify integrity with arj t *. Re-download if errors occur.
Multi-part archives: Ensure all .arj, .a01, .a02 files reside in the same directory before extraction.
Unsupported tools: Avoid ZIP-only utilities like older Windows Explorer versions.
