Thanks Ben Haven't tried it yet.. :) For windows.. it is easy .. compile your exe Dropped files are accessed via the global variables $0 - app name/path; $1 - dropped file 1; etc (see Help - Concepts & Techniques - The Outside World) So to access the full path to the first file dropped onto the app: put $1 into it On windows it didn't matter what sort of file was dropped.. it accepted everything .. files & folders. It then becomes a simple task of processing each variable $1 -> $n (n - the last file). I don't have any folders with thousands of files so I really don't know the limit of files it will accept. Any1 any1? thanks alex _______________________________________________ metacard mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/metacard
