Model files do not appear when attempting to import

[ebandiera]

I am attempting to import models from HLA. I have tried to import both the .vmdl file and .vmdl_c file but neither of these show up inside of the directory. Is there some sort of prerequisite for the files to be compatible, or is it possible that these files are just not able to be imported at all? I feel like I'm missing something very simple with the import process. Model examples are below, any help would be greatly appreciated.

Edit: I have attempted to use this with both Blender 2.82 and 2.80 with no luck so far.
Update: Got it working, just had the filtering turned on for the file names. I knew it would be a simple fix.
