About Szyszka
Szyszka is an open source bulk file renamer with a graphical interface built with GTK 4. Users combine rules that replace, trim, add, or purge text, add numbers, or change letter case. Custom rules can be saved and reused later, and rules and results can be edited and reordered.
The project lists Linux, macOS, and Windows support. On Linux, GTK 4.6 must be installed, which is bundled in Ubuntu 22.04 and newer. The macOS instructions are marked as not tested by the project. The Windows release zip includes its dependencies. Installation options listed include precompiled binaries, Snap, Cargo, and Gentoo's GURU overlay. The Flatpak entry is marked TODO.
