Hi , I need to write a batch script which will unzip the .Zip files from a folder and each .Zip file will have some .csv files inside,I need to unzip all the Zip files and appened the last 3 charcters of the .Zip file to the file name as below. Zip file name - XYZ_2_21.Zip and inside these zip I have 3 .csv files. My output should be firstfile_2_21.csv secondFile_2_21.csv thirdfile_2_21.csv How can I write the batch script to acheive this. --Sunitha

how are the files named inside the zipfile? (ie what, if any, extension). you would need to put the unzipped files into their own directory unless they have unique extensions. begin with: @echo off & setlocal EnableDelayedExpansion :make/change to temp directory md temp copy test.zip temp cd temp pkunzip test.zip :if they always have a 3-byte extension, it's pretty simple: for %%a in (*.*) do ( :same from here down both versions set c=%%a set c=!c:~0,-4! set c=!c!.csv ren %%a !c!) if the extensions are unique such that the files won't be mixed up with existing files, you wouldn't need to do any of the directory operations, just change the *.* to the unique extension. for ex. if extension is "txt" AND there are no files with .txt extension in the current working dir.: @echo off & setlocal EnableDelayedExpansion pkunzip test.zip for %%a in (*.txt) do ( and the rest would be the same from that point. if the files inside the zipfile have various lengths of extensions and not always 3 chars, you would need more code to locate the dot then chop it off. without more specfic info, can't tell you much better than this.
