If you are storing a library of 50 to 100 games, this can mean managing over 2.5 terabytes of data. Standard compression tools like WinRAR or 7zip can help, but they are general-purpose and often slow, as they compress data at a granular level without fully understanding the structure of a disc image.
However, the modding and emulation community has a strong Linux presence. Because the source code is available on GitHub, users have ported the tool to Linux by making minor modifications to the source (such as replacing Windows-specific file functions like _fseeki64 with standard POSIX functions). If you are on Linux, you can either compile it from source using gcc or look for community builds (like the fork by John-Gee) that work under Wine or natively on Linux systems. WudCompress
