Ubisoft loads you up with bloat you don’t need in all their games. This has become more prevalent with bigger and bigger releases from them (remember when origins was only 70 gb?). Here is how to make AC Valhalla take up less storage.
Remove Languages
First rick click the game in your steam library. Hover over “manage” and click browse local files. Should put you in the Assassin’s Creed Valhalla folder of your common folder.
12 GB: Open the sound data folder, inside it is a pc folder. Delete every file that does not have the language you are using or “sfx” in it.
Optional quality of life choice. This doesn’t save much space, only around 14 mb, but if you go to the videos tab and delete every language folder (make sure not to delete skills), it removes the launch screen videos. Make sure to delete the ubisoft logo, amd logo, and anvil logo videos as well.
Remove DLC You May Not Have
Within the AC Valhalla folder there are the major dlc folders. These sizes assume you already removed the languages Just delete the folder of any dlc you do not have.
11 gb: Wrath of the Druids-DLC 20
14 gb: The Forgotten Saga-DLC 35 (This is free however)
14 gb: Dawn of Ragnarök-DLC 148
9 gb: Siege of France-DLC 207
For any dlc you do keep, make sure to also remove the language files within there is 3.4 GB in total. Just delete every different language file except sfx and your primary one of course.
Extra Info
24 gb: DLC 211. Not actually sure what this is. Deleting it screws up the in game store, and says I am missing a blank dlc on my save. I try to load, i’m able to move in the animus area. I have no clothes but I have my weapons, and then it crashes after 3 seconds. Tried deleting some of the individual larger files within, no dice. Im assuming this is more misc stuff added over updates.
4 gb (x2): Not sure what 232 and 248 are, Best guess is the Odyssey crossover stuff is maybe one of them, but it doesn’t explain what the other could be.
Rest of the dlc folders are less than a gb in size.
If for some reason you want any of the content back, if you verify the integrity of the game within properties, it will add back everything included in the original install. When testing I just removed stuff from the folder but didn’t delete it just in case I needed to add it back.
