I can only advise how I would try to achieve, bear in mind that I am basically lazy....
I have all my .bat files (all seven of them) in a folder named BAT which is in my PATH so I don't have to use the full Path to any .bat file when accessing it.
So I would create the Image Concealer file and Save it in the Bat folder as say Conceal.bat
Next I would create another 'master' .bat file which will be used to CD and call Conceal.bat. Assuming you are first accessing the Command Prompt (CMD.EXE) and are at the C: prompt, and you have a primary directory named Tracks and a sub-directory named Films it would look something like:
cd tracks (default directory is now Tracks)
call Conceal.bat
cd Films (default directory is now Tracks/Films)
call Conceal.bat
cd .. (return to the Films parent directory {Tracks})
cd NextDirectory (default directory is now NextDirectory)
OK, I agree it's pretty crude - will it work - try it
The cd commands could be included in Conceal.bat and the file could be run minimized from a desktop shortcut - there are many methods, the above is just one.
Good luck
p.s.
Here are the NT commands CD(ChDir {Change Directory}) is one of them. If you go with my post above you will have to understand CD, please post back with what you don't understand and one of us will assist.
