WinRAR - Archive Manager

WinRAR is an archive manager for Windows that compresses and extracts files. It handles RAR, ZIP, 7z, TAR, GZ, ISO, CAB, and a dozen other formats. The program has been around since 1995, made by Alexander Roshal (RARLAB). It is shareware - you get a 40-day trial, after which it keeps working but shows a "please buy" popup every time you open it.

The installer is about 4 MB. Current stable version is 7.10. Windows only, 32-bit and 64-bit.

What it does

Right-click any archive and you get "Extract here" or "Extract to folder." Works the other way too - select files, right-click, "Add to archive." You pick between RAR format (better compression, repair records, encryption) or ZIP (everyone can open it). Compression methods range from Store (no compression, fast) to Best (smallest file, slowest).

AES-256 encryption lets you password-protect archives. There is an option to encrypt file names too, so nobody can even see what is inside without the password. You can split large archives into parts for USB sticks or upload limits - set "Split to volumes" to something like 700 MB or 2 GB and WinRAR creates numbered parts.

Self-extracting archives (SFX) create .exe files that unpack themselves without needing WinRAR installed on the other end. Repair records let you recover damaged archives if a few bytes got corrupted during transfer. WinRAR also opens ISO files, which is handy when you just need to pull a file out of a disc image without mounting it.

Advantages

  • Opens almost every archive format (RAR, ZIP, 7z, TAR, ISO, CAB, and more)
  • AES-256 encryption with file name hiding
  • Split archives into parts of any size
  • Self-extracting archives for recipients without WinRAR
  • Repair records to recover damaged archives
  • Small installer (~4 MB), fast

Drawbacks

  • Not free - shareware with a nag popup after 40 days
  • Windows only (no Mac or Linux version)
  • 7-Zip is free and handles most of the same formats
  • RAR format is proprietary - only WinRAR creates RAR files
Editor's take

WinRAR is one of those programs that everybody has used and almost nobody has paid for. The nag popup is easy to dismiss and the program never stops working, which is either generous or a strange business model depending on how you look at it. It does what it says - compression, extraction, encryption - and does it fast.

The honest question is whether you need it when 7-Zip exists and is completely free. If you regularly deal with RAR files or need self-extracting archives and repair records, WinRAR is the better tool. For everything else, 7-Zip works fine.

Who it is for

WinRAR is for anyone who works with compressed files on Windows. It is especially useful if you receive RAR archives regularly, need password-protected archives with AES encryption, or want to split large files into parts. If you only need basic ZIP extraction, Windows can do that natively, and 7-Zip covers the rest for free.
