Change "time" annotation lenght in file name

To achieve a perfect time allocation I changed the file names in the format : YYYYMMDD_HHMMSS_abcdefg getting these info from exhif record.
Unfotunately by mistake I renamed some as YYYYMMDD_HHMM_abcdefg missing the SS (Seconds). This makes the time sort of windows to fail the right order.
Now I must add the SS (from ehif record) to the wrong file names (many hundreds with the wrong name mixed up with hundreds with the correct one).
Any suggestion?

Hi Marcello,
you can remove the time format in all filenames (wrong or not) with the replace method using the regular expression this way:
Replace: (.*)_(.*)_(.*)
Replace with: \1_\3
Next, use the add method to add the time format from exif to all filenames at index 10.
You can now start the batch to get the desired filenames.

Hi Styb

Based on your suggestion I worked out a "Replace" expression fitting with my name rules

Problem solved.

Many Thanks Styb !!
