... nor "safe" to do so even if it works ...
I have seen at least one problem reported here that I suspect may have been due to a relocated data directory.
I have been doing this for Years...
And have NEVER had a problem related to the Data folder being located on an External Drive.
But I do Emphasize, if you are a novice PC user, this is not for you.
You must be familiar with making registry Edits, which are 100% Safe.
You must understand File Paths, and how to Create / find them.
You must understand how to Create and Edit Shortcuts.
And you Must manually Copy the BIN folder to the External Location each time you Install or Update.
You, the USER are responsible for being able to do all of the Above.
if you are a novice, then this is not for you.
Always Copy your Files and Make sure they Work, before you Delete them.
I never MOVE my Files. I do it in
Three StepsCopy to the new Location
Test that they work from the new Location
Then Delete them from the Original Location.
