Corrupt map files

I have 2 corrupt files on my 62s. They are both tile files from Topo Canada V4 . One is on the internal drive in gmapbmap folder , while the other is on a Backroads micro sd card also in the bmapgmap folder . They both say "corrupt" when I double click on them . Can I remove/delete these corrupt files and install new files ? If I can install new files what folder do I put them ?
