Hi @BurnsideAdmin
If you are looking to change the location that a particular app uses to store files, then yes, definitely check out the documentation on File Management and you can change the location(s) somewhere within the app code itself.
If your question is more related to where AppStudio itself stores the folders containing the apps that you create, then another option is to use standard Windows directory junctions to point elsewhere.
You could create a directory junction to point that entire directory (C:\Users\Me\ArcGIS\AppStudio\Apps) elsewhere, or you could do this individually for certain apps. I do this occasionally in situations where I want the AppStudio application code stored as a subfolder as part of a larger project that might, say, be included in a GitHub repo.
Look up the Windows "mklink /J" command online for more info.
