Hacking format wii system memory

[FGCinHB]

over the years I've add and removed alot of wads to my wii but was unaware I needed to use wadmanager to uninstall them, I just deleted the channels. now my wii only had a couple of hundered blocks left on it with no saves and cgfloader channel on the menu, if i format my system memory will it remove all the left over junk? I have softmodded 4.2u, I don't mind remodding it if I can get my blocks back over 1000.

Why not just move the things that are taking up so much space to an SD card?
