Please post your code, as bad or as little as it is, it really helps, the FormatDateTime takes your locals in account, i'm in Flanders, Europe so my system adds _19062012.ext but on your system it should be _06192012.ext set oFso = createobject('scripting.filesystemobject') sDirectorypath = 'c: testing' rename_files(sDirectorypath) sub rename_files(folder) set oFolder = oFso. Rock Band 3 Pc Game. getfolder(folder) for each oFile in oFolder.files new_name = oFile & '_' & replace(FormatDateTime(now,2),'/',') & '.' & oFso.GetExtensionName(oFile) wscript.echo 'renaming ' & oFile & ' =>' & new_name errResult = oFso.MoveFile(oFile, new_name) next for each oSubFolder in oFolder.subfolders rename_files(oSubFolder) next end sub.
