: You must have all parts (including part2.rar ) in the same folder before beginning. Ensure they are the same size to avoid corruption.
Are you installing the game, or are you adding kit mods to an existing copy of FIFA 23 ?
If you are modding , the "AIO" likely refers to the Ultimate AIO Kits V2 or similar packs which add hundreds of authentic kits, minifaces, and fonts.
: Right-click on Part 1 and select "Extract Here" using WinRAR . It will automatically pull data from part2.rar and the remaining segments to create a single setup folder.
: If extraction fails at the 15-20% mark, part2.rar is likely corrupted and needs to be redownloaded.
: These mods require the FIFA Mod Manager (v1.1.3 or higher). Process :
: If WinRAR asks for Part 2 during extraction, make sure the file name matches the others exactly (e.g., if Part 1 is Mod_AIO.part1.rar , Part 2 must be Mod_AIO.part2.rar ).
