Hi, I need to delete all the files more than 90 days old using msdos command script . What parameters do I use with "delete" command? Thanks

XP has no MS-DOS, therefore you need to use CMD.exe NT COMMAND PROMPT commands: http://www.ss64.com/nt/ http://www.ss64.com/nt/syntax.html

here is solution using vbs/wscript/cscript/wsh/wsf, okay, i am not really sure about what's it called. it looks like vb to me. this is my first attempt, so i am not responsible for any damage done. to run, type: cscript datediff.vbs or just datediff 'datediff.vbs - delete files 90days old (last modified) Set fs = CreateObject("Scripting.FileSystemObject") for each f in fs.getfolder(".").Files if Datediff("d",date,f.DateLastModified) < -90 then wscript.echo f.DateLastModified & " " & f.name 'f.delete end if next when you are sure it displays the correct file(s), remove the comment on line f.delete for the cmd.exe script, it involves date math. i think someone will eventually come up with a solution.
