Hi, I have a problem with opening m file.
After I change my cpu and gpu, m file opening takes about a minute.
I also reinstalled the matlab, but it didn't solve anything.
Could it be a problem to just use Window without activation?
Please help

@seokwon OH I am sorry idk what the problem is but I am curious if you can answer these questions:
1) how do you open the file? Is matlab already open? Is it via "Open" button or clicking in the "current folder". Or is matlab closed and you double click the file. What about if you type "edit <filename>" in command window.
2) what about if the file is renamed with different extension like .txt or what about .mlx files (also slow?)
3) If you open the .m file with notepad or vscode is it fast? or just as slow
4) How big is the .m file
5) what version of matlab

Hi
1) I open .m file via double clicking. And i just open by "open" button , it is still too slow. Both case was implemented while matlab(2021b) is already open. Edit<filename> took many ,too.
2)Renamed txt or mlx extension is very fast
3)It's fast (a second maybe)
4)It's not that big(about 5KB on average)
5)2021b
Thank you
plus) when I open .m file in specific folder, other .m file in that folder doesn't take long(it's fast). But if i open .m file in different folder at the same time, it takes too long.

Do you have a folder in Matlab's PATH, which is stored on a network drive or e.g. Dropbox? Then Matlab might scan the remote folder during opening the file. Accoring to the network speed, this can take a lot of time.
Try to reset the PATH temporarily.

No, those are not on my matlab path. Recently I migrated windows and file. Is it can be a problem?
