Creating a time-stamp in windows can be usful for the automated backups we all SHOULD be doing 🙂
pkzip c:\<source>\*.* c:\<target>\TempZip.zip
ren C:\<target>\TempZip.Zip c:\<target>\TempZip_%date:~-4,4%%date:~-7,2%%date:~-10,2%.zip
Or simply to create a directory for copying open files (Lawrence 🙂 )
set backdir=%date:~-4,4%%date:~-7,2%%date:~-10,2%
mkdir %backdir%
cd %backdir%
etc..
