Probably a bug
Even when the binaries are present it is showing they aren't
only happens with binaries with suffix '.exe'

Thanks for this, I will fix this.

What about a preprocessor section in which we can assign specific preprocessor other then which can be used with freearc to the specific files not always dependent on masks
something like ogg comes with UltraARC but user define and not masks dependent but we can make our own list
for Example GTA V, it has all major files with extension .rpf but only some of them can be process with something like reflate and other are incompressible multimedia containers.

I was thinking about how to set up such a thing, I wanted to extend the possibilities of the filter tab, to create a "masked group" and "masked filter" in order to simplify the creation of custom methodes depending on the type of data.

and also if the program is single threaded if arcGUI can feature multi TASK

When you say "multi TASK", you mean several execution simultaneously?

and one more thing let the arcGUI to search in %PATH% for arc.exe

I will add this, it will be for the next version

Thanks for feedback, very Useful.
