Batch File - rename 220 files

Hi,

I am running Windows Vista Home Premium.

I have a directory that contains 220 files that I want to rename.

The format of some files are as follows:

fileName fileNumber fileSecondaryName (common name).txt

Other files are like:
file Name fileNumber fileSecondaryName (common.name).txt

The only differences are the space in "file name" at the beginning and a period in between the two words in the brackets.

I am after a script that will rename these files by deleting the "fileName or "file name"" and "(common name)" or "(common.name)", including the brackets, from the file name.

That is to:
fileNumber fileSecondaryName.txt


Can anyone help?

Regards
Noobie

Thank you

I have been just thinking. It doesn't have to be a windows batch script. I will accept a program in any language as long as it does the job.

I am not sure I understand your request...

can you give an exact example of some of the actual file names?

you may not need a script unless this task is going to be needed to be repeated...you may be able to use a "find and replace" application?

Yes this task will need to be repeated on a regular basis but where the file names are slightly different but follow a similar format.

So something which I can edit, if needed, would be ideal.

Here are some actual file names:

testScript [2x01] add new sales record (asd.open)
testScript [2x02] delete existing sales record (asd open)
testScript [2x03] modify existing sales record (asd.open)

Thank you in advance.
