Since you are using XP and not pure DOS, there is no lack of tools that can find the date for you. eg of some of them are Perl/Python..which are better than batch to do such things. If you are not restricted to only batch, you can download Windows services for Unix at http://technet.microsoft.com/en-us/... It brings Unix to Windows environment. Once you installed, you can just use the korn shell and do this: find /dev/fs/C -type d -mtime +3 -print. This will print out the directories that are more than 3 days in your C drive. To remove them, you can pipe to rm command: find /dev/fs/C -type d -mtime +3 -print | xargs rm -f
