Merged files folder

Hello everyone,


I searched on the forum but i couldn't find my answer, so I'm calling your help !



I would like to get some free space in my internal HDD.

Some time ago I merged files XXXX.666** from my FAT32 external HDD into my internal one (I guess, right ?).

I'm running out of free space on my internal HDD, so I'd like to delete these "merged" files, but I don't know where they are localized.

If someone could give me a hand.



Thanks
