Correct way to move a project to a new drive?

[evanallred123]

The solution that worked for me, without editing GameUserSettings.ini, I found in this thread:

How do I migrate my entire Unreal file base to my other hard drive?

I initially installed Unreal through the default location, in the x86 folder. I have recently found out that I need to purge some files as my primary drive is full. My secondary, not so much. How do I move my existing projects from one drive to another; how do I ensure that the secondary drive is the default location for future projects?

Simply launching the Unreal project from the .uproject file in the new directory seems to make the Epic Launcher recognize it as a valid project, and it now appears in my project library.
