How do I edit this texconv “IMGtoBC3.bat” file so it “READS FROM & PRESERVES the directory structure when writing the ”resulting" dds files

Question

Like the title says:

How do I edit this texconv "IMGtoBC3.bat" file so it "READS FROM & PRESERVES the directory structure when writing the "resulting" dds files?

THIS IS FOR END USERS, OF A GAME MOD "EASY CUSTOM ASSET BUILDER"

• SO I NEED TO ALLOW "MANY" INSTALL LOCATIONS
• PLUS "ENDLESS" CUSTOM DIRECTORY STRUCTURES OF INPUT FILES inside the "directed to use "folders""

I have a large folder/sub-folders with many tiff's that "have the same file name" divided up into "sets".

These dds files are for custom textures in a unity game, file naming is a forced event, but "sorted/selected" by folder.

I have about 3000 file sets ready to convert and I'm not doing them 1 by 1 in Nvidia tool (I hope) and AMD tool and the game have a MAJOR conflict (its as a no go)

BONUS points to anyone that could show me this "bat" file using unity's new tree of "CRUNCH" cmd line dds compressor/encoder. Suggestions of other tools: I have tested over 50 apps, for my needs its: Nvidia, texconv and then crunch in level of quality/support

HERE IS THE CODE:
