What is a .LHA file?
LHA is a compressed archive from the LHarc tool, especially popular in Japan.
- Did you know
- The tool behind .lha was briefly called just LH, but was renamed LHA when MS-DOS 5.0 arrived with a built-in LH (load high) command of the same name.
- Such was the format’s popularity in Japan that Microsoft shipped an official Compressed (LZH) Folder add-on for Japanese Windows XP, and built it into the Japanese edition of Windows 7.
- In 2010 the developer of UNLHA32.DLL ended development and advised users to abandon the format, after crafted archive headers proved able to slip past antivirus scanners.
- What Analyser reads
- Read software packages and Unix archive streams: Python wheels, NuGet, Chrome/Firefox/VS Code extensions, Electron ASAR, Windows APPX/MSIX, Debian (DEB), RPM, RubyGems, conda, Anki, Microsoft CAB, cpio and ar - showing name, version, dependencies and the file tree.
- Depth of analysis
- .LHA is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .LHA file
- Drag a .LHA file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
