i believe this is output for one of TK's mods (tk dodge, ultimate combat, and "tk something" i forget)...fore mentions this on his nexus mod page description for version 6.3 he is quoted as saying this needs to go into the FNIS output folder, and if you're using mod organizer will ask if you want to overwrite the meshes folder (say yes)...i don't believe anything bad will happen if you output the txt file to another custom 'mod' via right clicking overwrite file in MO (the file gets created upon game launch along with a few SKSE plugins)
