I've used the app and it does what is expected, thanks Ian.
Although i have a sugestion.
Since whenever you perform one operation of this kind on sensitive files we usually do a back-up on them, probably it would be better if the application didn't require the folder tree to be similar as an original lfs installation.
I say this because i never use this app's on the program folder, i imported the settings folder to a temp folder and try to use the app there, but i had to create a lfs similar folder structure for the app to run, something like this:
and manually had to create
Prolly the app could function within the 'data' folder only, and also create the folders 'setups' and also 'colours', explorer would then ask if you want to replace the files within those folders, if you do it in the lfs root folder, or ask nothing and directly create the folders if you do it like i did.
I don´t understand nothing of programming so don't ask anything about or smack because i didn't imediatly see that its impossible to achieve what i sugest here
Thanks and regards
