why does Microstation increment Pref folder?

This is normally related to different versions of the software used ie CE update 12, 13, 14

We are only using Microstation Connect update 14.

If I copy a PCF or UCF into it the 10.0.0\Pref folder. Microstation will create a new folder and use it.

Why does this happen?

Hi rpsmith,

I would recommend checking out this Wiki for guidance:
https://communities.bentley.com/products/microstation/w/microstation__wiki/63856/how-to-reset-temp-folder-versions

From my testing, the 10.0.0_x folder will be created if the .txt file with random characters is not already in this directory:
C:\Users\<username>\AppData\Local\Bentley\MicroStation\10.0.0\

I have been doing a lot of research into this. 

If you are not aware, there are two folders called 10.0.0.  If either of them are not updated and contian the files that are installed by default, then you get the incremented folder.

C:\Users\[USERNAME]\AppData\Local\Bentley\MicroStation\10.0.0

C:\Users\[USERNAME]\\AppData\Local\Temp\Bentley\MicroStation\10.0.0

To stop this, I have created a copy of both 10.0.0 folders on a server and copy both to each PC when the new user uses MicroStation.

below is a mockup of what I am referring too

\\server\Bentley_install\MicroStationV17.2\Local\10.0.0

\\server\Bentley_install\MicroStationV17.2\Temp\10.0.0

Thanks for the info Ian.
In addition, it would be a good idea to check the following directories (you've already listed two). If there are any 10.0.0_x folders in these locations, remove them after uninstalling MicroStation, and then install the latest version which will reset the folders.

%LOCALAPPDATA%\Bentley\MicroStation

%APPDATA%\Bentley\MicroStation

%PROGRAMDATA%\Bentley\MicroStation

%LOCALAPPDATA%\Temp\Bentley\MicroStation
