I have a cmd line ( extract.exe ) that decompres a specific encrypted data files ( .prs ). the parameters are like this: extract.exe -e input output ( Example: extract.exe -e 0001.prs 0001.prs.dec This will decompress 0001.prs into a new file 0001.prs.dec ) Now i have a directory with a LOT of these .prs files, and i would like to write a simple batch to decompress them all rapidly using the extract.exe How can I do? Thanks! :D

0001.prs.dec is *NOT* a DOS file name. wrong forum But as long as you're here, in XP: --------------------------------- @echo off & setLocal EnableDELAYedExpansion for /f "tokens=* delims= " %%a in ('dir/b *.prs') do ( extract.exe -e %%a %%a.dec ) ===================================== Helping others achieve escape felicity M2

sorry for the wrong forum, and thx for the perfect response... it works great! ^_^
