Firstly, I'm no expert on this so someone with more Amiga knowledge please feel free to jump in at any time
So, it's my understanding that Amiga file attributes are as follows:
Windows / MAC computer don't have the same file attributes so if you copy from one of these computers and say a file had "Script" set then it must get lost?
Isn't this the same issue that people have sometimes with WHDLoad files i.e. extracting on a computer as opposed to an Amiga?
