Allow additional Experimental installation
New, WishlistPublic


As of 54.x Experimental, a former workaround to quickly switch from Stable to Experimental and vice versa by copying/swapping a DayZ folder containing the respective other version in the Steamapps/common folder is no longer working.

Steam then does not recognize it (checking integrity of game files will fail with over a hundred files, several GB, e.g. the whole game having to be reacquired).

Steps To Reproduce
  • Let Steam update DayZ without opting into Experimental.
  • Copy the folder "DayZ" in ...Steam/Steamapps/common to some other location.
  • Start Steam, right-click on DayZ, select Properties, Betas, opt in to Experimental.
  • Steam will then download the necessary files for Experimental version, overwriting the Stable install.
  • To switch back, you normally would have to opt out and let Steam then reacquire around 5 GB.
  • To prevent that, a popular workaround suggested just using such a manual backup of the game folder (Steam/Steamapps/common/DayZ).
  • This is no longer working, Steam now re-downloads the entire game regardless of such a manual restoring operation. While I can't rule out the possibility that it's only me and my machine somehow, at least here it was reproducible.
Additional Information

Since Steam usually allows this kind of using a manual backup without problems with all games (you can have a fresh installation of Steam and actually move a complete backup of all your games there, only a couple of hundred Megs will have to be downloaded again), I guess something is wrong on the DayZ side in that respect. But even if it should actually be a Steam issue:

Why not get rid of the need for that workaround altogether and let people have two installations of DayZ all the time, one with an Experimental, the other with the Stable version? There will be two versions of DaySA for a long long time anyway... and making it easier for people to try out the experimental stuff on the fly should be welcomed by the Devs I guess.

Btw, the reason I found out was that I wanted to return to stable immediately after seeing that ungodly awful new server browser window :p
