Right. So in case someone writes a script or program to 1) rename one set of pics to another, and 2) move them from one places to another places, how might the information necessary to do that, be represented on a spreadsheet?
Left column is the three letter set code used by wotc.
Right column is the set code that Forge uses.
Anything else? How to handle subdirectories?
