Let me point out the below.
It is more than obvious that the DA and TMC svgs that are included in Alains A_DA_TMC.zip or my N_GreeK_mod_UX.zip have priority over the ones located in the original zip files like Driveralerts.zp, TMC.zip, global_cfg.zip etc.
Same thing applies in most of the original UX zip files. They can be handled by any additional zip file which contains same folder and file structure.
But What is the rationale behind it?
It has nothing to do with the alphabetical order of the zip file name or its name by it shelf. These additional zip files can be named with any name you like (letters or numbers) and if the folder structure (inside it) is like the originals they take the lead. The contents of them like svgs or other files that have the same name with the originals will have priority over them.
I searched also about file association or correlation but I couldn’t find anything. Is it iGO hard coded? Did I miss a code inside a basic file located in the_skin_by_Pongo.zip file or somewhere else?
