FAQ
A compressor failed. What do I do?
Take a screenshot of the error and back up your data. Try a different method. Errors usually come from the tools themselves, not MiniCompressor.
Why can't I use DiskSpan with Masked Compression?
DiskSpan splits files while Masked modifies data streams. Used together they cause corruption. Use one or the other.
How do I pick the right Oodle version for my game?
Check the game folder for oo2core_X_win64.dll. The number in the filename is your version. Set it under Options → Oodle Version.
Is it free?
Yes, completely free and open source under GPL-3.0.
How do I update?
Help → Check for Updates, or grab the latest from the Releases page.
