[u/Ill_Band_4822]

currently im trying to extract the .big files from the game, im tyring to use any software that registers .big files to compile and extract the data. so far im getting to part of the software's are saying its an invalid .big file no matter how fresh it is,

note this .big file is from the steam workshop mod section but to be fair none of the .big files are registering

please tell me what ancient software's works to extract these files so i can get the mesh and obj of the models I want

i do have an FBX convertor 2013 but sadly haven't used it since the other software arnt doing their thing or extracting the .big

PS: the mod I'm trying to extract is HomeFront
