Save this as "rename.vbs" in the target directory.

Edit it so that the sPath is the name of the folder, and the sExt
is the name of the extension you wish to check (to filter for
just .gif files, for example).


Double click it in Windows Explorer and it should do the trick.

sPath = "c:\temp\folder\"
sExt = ".gif"


Set fsoObject = CreateObject("Scripting.FileSystemObject")
Set fsoFolder = fsoObject.GetFolder(sPath)
for each fsoFile in fsoFolder.Files
if (Right(fsoFile.Name, Len(sExt)) = sExt) then
sNewName = Replace(fsoFile.Name, ".", "_rev1.")
fsoFile.Name = LCase(sNewName)
end if

Set fsoFolder = Nothing
