Thank you. I forgot the exact directory.

There are 2 options that you can use.  First is the default way.

#1.  C:/Program Files/Steam/SteamApps/common/7 days to die/Mods/

Second way and the way you should be installing mods is like this.

#2.  C:/Users/"Your User Name"/AppData/Roaming/7DaysToDie/Mods/

While using the default way, you will have to use caution NOT to delete or over-write the 0_TFP_Harmony file.  If you do, the game won't run, and you will have to verify file integrity to get it back.  The second way keeps everything simple, neat and tidy.  If you're into world or prefab editing, your work will be saved here.  So, no need to go searching around for anything.  And if you delete your Mods folder from here, no harm will come to your game.

By the way.  I have been posting progress updates on the discord channel covering all the fixes I have been making along the way.  I am still finding small bugs and patching them as I go.  Most are just tiny .xml changes and won't affect the server's clients.  When you see the mods pack date change on the steam server browser page, that is when you need to download the latest pack.

Many vids now about NOT going to WIN 11 but to Linux instead:

Is it possible to still keep Windows 10 alive for a few more years?

Videos (very recent) on how Windows 11 (25H2 update) broke computers

Yup.  That's all there is to it.

Thank you. I forgot the exact directory.
