Just wondering, if it’s possible to, monitor a certain folder XXX, and its sub folders, and rename certain extension to another. Like
Monitor And change

1.
If you are using the Desktop application, then you can use Plain File Mode and set Extension: Override.


2.
If you are using the command-line, then you'll want to use a simple shell script:

"volume1" suggests that you're using Synology NAS. Debian tools such as rename and inotifywait that we would typically use for this kind of use case might not be available. However, the solution in the link above only uses find and mv so it'll work on any Linux machine, and we can then use Synology Scheduler to call that automatically once a day.
