Q: How do I remove the prefixes/tags under Linux?
A:
1. change into the directory where your files reside 2. Backup the files everything in that folder 3. run: rename 's/^__[0-9]{6}__//' __*__* -v
Note: Works only if the prefix are 2 underscores,
followed by 6 numbers, followed by 2 underscores.
Where rename is a command in a linux terminal.
