I just found out that paths to external diff tools won't work if they contain spaces somewhere. In my case I want to find differences in file1.txt and file2.txt:
c:\Portable\1gb Stick\_Software\office\PSPad\file1.txt c:\Portable\1gb Stick\_Software\office\PSPad\file2.txt This path is transferred to the external diff tool as _c:\Portable\1gb_ (for the first file) and _Stick\_Software\office\PSPad\file2.txt_ (for the second file) -- <http://forum.pspad.com/read.php?4,66481,66481> PSPad freeware editor http://www.pspad.com
