If not explicitly said, all tools are programmed in Delphi 7 and compiled for Windows. If you want to use them on Linux, you are in a disadvantage. GUI things should probably run in Wine, and some command-line tools can be probably compiled in FreePascal.

I am not going to take any responsibility for whatever happens to your data when using these programs. I can only say that none of them should be harmful - I know it better than anyone else; however viruses are a today internet's threat and I must advise you to scan everything including my programs.
