RAR is an archive format. Modern Windows versions may support more archive formats natively, but Windows 10 generally requires a reputable archive utility to open/extract RAR files.
Steps
- Download a maintained archive utility such as 7-Zip or WinRAR from its official publisher.
- Install it, then right-click the RAR file and choose the utility’s Open or Extract option.
- Choose a destination folder and extract the contents rather than running unknown files directly from the archive.
- Scan/inspect extracted files before opening executables or scripts.
- If the archive is multipart, keep all `.part1.rar`, `.part2.rar`, etc. files together and start extraction from the first part.
How it works
Opening an archive displays its contents; extraction creates normal files on disk. Password-protected archives require the correct password and may use encryption.
Important considerations
Windows 10 is unsupported. Treat unsolicited password-protected archives as suspicious because they are often used to evade email/security scanning.
Practical guidance
7-Zip can extract many RAR archives, while WinRAR is the format’s original commercial utility and may support the newest RAR features sooner. Download either only from its official site. After extraction, the `.rar` can be retained as an archive or deleted only after you verify the extracted files.
Additional details
Do not confuse RAR extraction with converting the archive. You normally extract the files and use them in their original formats. If Windows says the archive is damaged, re-download it from a trusted source or verify all multipart pieces; repeatedly trying different extractors cannot restore missing archive data.
