I have many SD cards that I rename with the person whose card it is. I'd like to use the file renaming protocol for video files (in this case) to rename by date, time and the name of the person (ie the name of the SD card that is the target folder for the rules). I only seem to be able to add the entire file path or the name of the sub folder instead of being able to create a generic rule to add to all rules that just inserts the name of the SD card.
To clarify, the SD card called 'Kevin' has a few sub folders, in which is a video. I want to rename it to be 2016-05-18_1521_Kevin.mpg, for instance. At present I have to add 'Kevin' into the rule for each card. I'd like to do that on a generic level. I can either add "//Volumes/Kevin/Aim/Otherfolder/" or "Otherfolder" with the rules now, based on my fumbling testing.
Any ideas?
