Windows Batch File, how to rename and remove part of filename

Question

I am trying to rename a group of files in a directory that all have a part in the filename I want removed later on. The example of names are:

1. 123876. 111 thepartIwanttoremove.exe
2. thisisatestfile. 111 thepartIwanttoremove.exe

3. this?392!. 111 thepartIwanttoremove.exe

4. thankyouall. 222 thepartIwanttoremove.exe

5. test. 222 thepartIwanttoremove.exe
6. whatis@d354. 222 thepartIwanttoremove.exe

My code is:

forfiles /S /M *.111thepartIwanttoremove.exe /C "cmd /c rename @file @fname.doc"
ren ???.111thepartIwanttoremove.* ???.doc
ren ????.111thepartIwanttoremove.* ????.doc
ren ?????.111thepartIwanttoremove.* ?????.doc (and so on)

forfiles /S /M *.222thepartIwanttoremove.exe /C "cmd /c rename @file @fname.jpg"
ren ???.222thepartIwanttoremove.* ???.jpg
ren ????.222thepartIwanttoremove.* ????.jpg
ren ?????.222thepartIwanttoremove.* ?????.jpg (and so on)

So for an example I want the file:

123876.111thepartIwanttoremove.exe

To look like this:

123876.doc

what function can I use to remove the .*thepartIwanttoremove.exe part of the name afterwards without writing so many lines with "?"?

Thank you very much for your help.

Answer 1

Assuming all the files have three parts to the file name that are separated by periods, this style of code should work for you.

for /F "tokens=1-3 delims=." %%G in ('dir /a-d /b *.111*.exe') do rename "%%G.%%H.%%I" "%%G.doc"
for /F "tokens=1-3 delims=." %%G in ('dir /a-d /b *.222*.exe') do rename "%%G.%%H.%%I" "%%G.jpg"
