For the past two years off and on I've been updating FileMaster to work with IcarosDesktop 64bit. The bgui requesters caused it to crash. Also the string handling and number handling were messed up. But now I have replaced some requesters and I'm fixing the strings and numerical functions. It works somewhat.
In the next few weeks I will add more requesters and fix more of it so that it can be used on a regular basis. If you prefer Dopus4 or Dopus Magellan an updated FileMaster may not interest you.
I also have found the sources from Christian Kummerow so at some point I may assemble a combined source with updates.
