Gzdoom work with no wad file!

 I downloaded the file NERVE.wad to play No Rest For The Living levels in gzdoom, put wad in base folder and play it. But now I deleting all the wads from the base folder and doom bfg edition and doom 2 bfg edition continues to get loaded!

How this is possible? I deleted all wad files, no wads files remain in anny folder!

Edit: Now all my doom games, heretic and hexen have doom bfg edition and doom 2 bfg edtion to load, even without wad in respects folders. Gzdoom use any commom folder to store wads?

It's loading them from your Steam/GOG install directory.

That because GZDOOM (and some source port) can load IWAD off Steam/GOG install directory.

Ah wow!
