0. if you can do what you want to do with the files where they are why do you need to move them?
1. if you can do the operation you want to do on one file you can most probably do it on all 10.000 files 2. If there are a lot of files you do not need you may want to delete them 3. if the directories have unique names and only one file in each you need with the same name in alll you may want to use the directory name as a filename 2011/11/22 Skip Cave <[email protected]> > The data structure I am working on has a directory structure that is > several levels deep.
