Is there a way to process and bulk rename a set of files based on a prefix appearing in their names such as
06-2023-SourceFileName.csv
07-2023-SourceFileName.csv
08-2023-SourceFileName.csv
09-2023-SourceFileName.csv
10-2023-SourceFileName.csv
11-2023-SourceFileName.csv
12-2023-SourceFileName.csv
to have the same multiple actions perform against each, have a new calculated column added where it derives the values based on the MM-YYYY prefix value from each file. (my options would be to keep the MM-YYYY value "as-is" for each record in each file or replace this value which I have done individually on column values before via multiple If conditions). Unfortunately, the Calculate new column option doesn't seem to show a way to interact with what the source file name is, only the columns names.
Does any option exist using a function or via using regex?
