[image] I ran this action on a group of files and it changed files even where a complete match was not found. Found example, it changed 'Cliff Richard' to 'Clifeat. Richard' and 'Daft Punk' to 'Dafeat. Punk'. I've tried it as replace with regular expression (results above) and replace (only as wh…

Thank you, your explanation is very good. That is not at all how I would have imagined it working, in my mind I thought it would look for the letters, space and full stop combined.

Following on from this, it seems that this is the best solution: Field: Artist, _Filename & Title Regular expression: (?i)(\s)f(?:ea)?t(?:(?:\.?|\s)|uring)(?=\s) Replace matches with: $1feat. [image]

After further testing, I am not sure why but there does appear to be a problem. This screenshot shows that the regex mentioned above adds unexpected data to the fields: [image] $! Do I replace this with a simple space and will that have the desired effect?

The screendump does not show the source fields. I would suspect that there is no match as e.g. the filename does not have a space in front of the various "feat" strings.
