I got tired of this exact problem, so I took the time to write a simple
windows .DLL file that has some basic file I/O routines (goodbye platform
independance). Then I wrote IDL wrapper functions to delete, move, rename,
and copy files and directories, as well as return file information like
creation date and time, etc.
Previously, before learning how to use 'call_external', I increased the
speed of multiple file operations by writing all the commands into a batch
file, and then using spawn only once to execute the batch file. This saved
time by only popping up one dos window.
good luck
