Rename files problem

[mqsymth]

I can't seem to get the rename a group of files to work properly.

I highlight 116 files

I want to rename part of the files name from

myfile010106.cvs to newfile010106.csv

for all 116 files that have 116 different dates other than 010106.

I would like to say
rename myfile* to newfile*
for all 116 highlighted files but I can't seem to do that

I can't find a way to do this.

What am I doing wrong?

Thanks for any help

That did it. Thanks!

Or, in case you like to play around with RegExp it can be done as well - probably not quite as simple for this task.
