Updating System

[cosmic rover]

Thanks for replying, like I said, i did use the command prompt and PowerShell using System.Diagnostics.Process. But when i use that, for some reason it still says the folder is in use (even with the app force stopeed in command prompt)

The "folder" or the exe task is in use? And do you have a print or some bool or something to confirm your console app actually ended the task? (and isnt still waiting for the task to respond/close)

When I try to delete the whole folder it says folder still in use.
I did try adding an sleep (wait) function before deleting the folder, still saying it is in use.
When I open the task manger, i see that it cmd (or powershell) is a child of the unity's exe.

Well Unity will always have powershell as a child, probably several since they are used for computing shaders and im sure other background activity both while running and closing the editor - if this is specific for a build, I think you should test in the exe build itself, as Unity might have some locks on editor files while the editor is open - if its for the editor specifically, and its not a folder you originally created (ie: its managed by Unity), then you might just have to add a sub-folder and control it that way

Though I would imagine usually youd be able to just force-close a folder even if its "in use" most apps just look at whats in a folder and thats about it, I cant see anything (even Unity) reserving access to a folder, unless its a Unity-created and managed folder like the Assets folder or something

I dont think you understand what im trying to do

Im trying to make an button the my app, where if you press it, it will download a zip file from google drive, then it extracts the zip file to the "Vidoes" folder. Then it opens command prompt. Command prompt goes and force stops the .exe file (the app). Then it trys to delete the old app version's folder, and then cut (copy and delete) the new version to the same directory.

But when i try to delete the folder, it gives me an error that the folder is still in use

When i look in the task manger, i see after command prompts froce stops the .exe file, the .exe file is still open, but with the Command prompt as one of its childs

Then you could probably just Application.Quit from Unity after launching your command prompt, and have your command prompt wait for that task to close itself before proceeding

AH, i did not think of that... Ill try that when I continue working on the updating system.

Thanks for the help!
