[Please note, the plugin I mention is NOT a finder substitute. It is a plugin, and merely gives the finder tabs.
If I disable this plugin, the result is the same in the "original" finder. Although when I say "original" I was using finder all along anyway.]
I shouldn't have mentioned it, it is superfluous info.
I dragged and dropped files using finder, that's all that needed to be said really.
It would obviously make no sense to ask questions about finder if I was not using finder.
Okay, I have to say, this is incredibly strange :
After comparing the two separate drives,
it seems I DID actually move the files to another folder [and forgot / was unsure of this],
however, the info box still says the original folder I mention is 60gb, with one file [which does not appear when I open it]
and finder is not displaying the increase in size in the folder [I'll call it folder 2] I moved the files to.
I wonder if I delete the original folder, are the sub-folders I moved to folder no.2 going to be deleted?
Are they still somehow connected to the original folder?
I was moving things around to try and merge all my files and folders into one folder [folder no.2]
