I want to add the same prefix to a large number of files, all with the same extension, but all having long file names with spaces in them. I found the following code at http://www.lagmonster.org/docs/DOS7/z-ren1.html:
LFNFOR On
FOR %v IN (*.txt) DO REN %v abc%v.x
REN *.x *
When I try it without LFNFOR, I get an error message - not surprising since I didn't specify long file names.
However, when I key in LFNFOR, I get an error message just from typing that.
My PC is 64-bit Windows 7.
Thanks in advance for your help.

To clarify, the DOS commands I cited should appear on separate lines, and somehow got placed onto one when my question was posted:
LFNFOR On
FOR %v IN (*.txt) DO REN %v abc%v.x
REN *.x *
It did it again! (There should be A carriage return after LFNFOR, and another one prior to REX *.x *)
You mean, like this?
(add a return, and four spaces per line for a code block)
