I was testing some things using ASSOC and FTYPE and got this strange error when removing my tests. The first time went just as expected, then I repeated it to double check it had been removed. I did not expect to see the error "The operation completed successfully." D:\>ftype zzztest D:\>ftype zzztestTCC: (Sys) The operation completed successfully. "zzztest\SHELL\OPEN\COMMAND" D:\>assoc .zzz D:\>assoc .zzzTCC: (Sys) The operation completed successfully. ".zzz" -- Jim Cook 2010 Sundays: 4/4, 6/6, 8/8, 10/10, 12/12 and 5/9, 9/5, 7/11, 11/7.
