About HA files
The .HA file extension identifies a legacy Compressed Archive created by the HA Archiver (developed by Harri Hirvola in 1993). Famous in the DOS and BBS era for its HSC compression algorithm, it offered superior compression ratios for text compared to ZIP but was notoriously slow to compress.
Today, users typically encounter .HA files when recovering old software, games, or data backups from the early 90s. The primary friction is that modern operating systems like Windows 11 and macOS lack native support, and even popular tools like the standard 7-Zip distribution may fail to open them without specific plugins. To use the contents, you must convert the archive to a modern standard.
For general accessibility, convert .HA to ZIP or 7Z. For archiving purposes, 7Z or RAR will maintain high compression ratios. The conversion process usually involves extracting the files using a compatible legacy-supported tool (like WinRAR) and repacking them.
Convert.Guru analyzes your HA file, detects the exact format, and lets you read the text inside.
If you want to convert HA file to M2, SQM, AC, KM, ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ or LZMA, you can use WinRAR or similar software from the "Legacy File Compression" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to HA, try WinRAR or another comparable tool in the "Legacy File Compression" category.
The HA Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HA converter.
