I have a bunch of files with names like:
tex_browser.gim.png
tex_camera.gim.png
tex_cnf_date.gim.png
...

Basically what I need to do is remove the ".gim" in the middle of them with by running a *.bat file. So they'll end up being named:

tex_browser.png
tex_camera.png
tex_cnf_date.png
...

Any batch file experts out there that can help me?

These guys are pro's. I think they covered this one in this thread. See if that helps ya! batch-rename-files-consecutive-n

Good Luck!

vbscript. Save as script.vbs and on command line,
c:\test> cscript /nologo script.vbs

Set objFS = CreateObject("Scripting.FileSystemObject")
strMyFolder = "C:\test"
For Each Files In objFS.GetFolder(strMyFolder).Files
	If InStr(objFS.GetFileName(Files),".gim.") > 0 Then
		strNewFile = Replace(objFS.GetFileName(Files),".gim.",".")
		Files.Name = strNewFile		
	End If 
Next

I've got nothing to do, so here's a one line Command Script.

@for %%a in (*.*) do @for %%b in ("%%~Na") do @ren "%%a" "%%~Nb%%~Xa"

That worked perfect, thanks Razor!
