I've installed MATLAB R2021a in disk D:, and I've kept my "AppData" folder at the default directory "C:\Users\(user name)\AppData". There DOES exist a folder "C:\Users\(user name)\AppData\Roaming\MathWorks\MATLAB\R2021a", but every time I use MATLAB R2021a, it creates a folder in disk E: with the directory "E:\Users\(user name)\AppData\Roaming\MathWorks\MATLAB\R2021a". This folder contains nothing and occupies 0 byte. Any other application does not create a similar folder in disk E:, either. What should I do to solve this problem?

在 MATLAB Online 中打开

You may try executing

userpath /my/custom/location

and then restart MATLAB.

I checked the path settings. I just filed a bug report.

Here is the answer from the MathWorks support:

Our development team is aware of this issue. Besides, the issue has already been resolved in the upcoming release of MATLAB (R2021b), but a robust solution does not currently exist for R2021a. Unfortunately, this means my best recommendation is to stick with an earlier release of MATLAB in which this issue is not present (R2020b or earlier) until the full release of MATLAB R2021b.

I changed the folder to "hidden".
