Can I change file names using wild cards in RapidMiner
Contributor I
My first posting 
I download a large number of files every week from an external vendor for RM processing. The process remains the same. However, the file names are slightly different every week because the vendor adds an identifier. When the number of files was small, I manually changed the file names. I would like to change the file names within RM, using an operator and wild cards. I would appreciate any suggestions.
I have tried rename file operator. It does not permit wildcards.
Thank you.

You could use the 'loop files' operator. This will set a macro corresponding to the file being processed and the inner operators to the loop operator can do what they like with this. I posted something similar here...

You could use this as a basis perhaps...
