If you want to make games looking like Quake this is the way to go lol
There must be some solutions :
1) zip all assets in one file, one file to laod is lot faster than loading thousand files, the engine dezip will be faster than manipulating IO files reading.
2) Use Atlas textures when it is possible
3) Use better textures compression
