Script is in biterscripting. Copy and paste the script into file C:/Scripts/DeleteBySize.txt, start biterscrpting, then copy and paste the following command into command area.

script "C:/Scripts/DeleteBySize.txt" folder("C:/testfolder") bytes(0)

Above command will delete all files in folder “C:/testfolder” whose file size is 0.

script "C:/Scripts/DeleteBySize.txt" folder("C:/testfolder") bytes(100)

will delete all files in folder “C:/testfolder” whose file size is less than or equal to 100.

etc.

Test the script first before using. The documentation for the lf (list files) command is at http://www.biterscripting.com/helppages/lf.html .

Hope this helps!
