Windows 10: How do I prevent one drive from deleting the files on my pc?

My one drive has become too full, when I try to manage the folders that are synced to one drive the program informs me that the files will remain on one drive and be deleted from my pc. I want the opposite to happen. How do I protect the files on my pc?

deleting hard drive files

Hi,

May we know what type of file are you trying to delete? Would it be Office documents, media files, or picture files? If you're trying to delete files for free some space on your device. We suggest to perform a Disc Cleanup. Kindly follow the steps below to
perform the task:

• Type in Cortana Disc Cleanup
  
• Choose the files to delete
  
• Click on "Clean up system files"
  
• Click on Ok
  

For any concerns, don't hesitate to get back to us.

Regards.

 

Deleting DVD Drive (F files

Hi,

Your file might be currently utilized by an application on your PC, preventing it from being used. You can delete the file by closing the application that is currently using your file. To do so, follow these steps:

• Search and open the Task Manager.
• On the Processes tab, search for the application which currently uses your file.
• Select the application and click End task.
• You can now delete the file.

Let us know how things go.

Regards.

How to prevent deletion of files in directory?

Using Windows Version 2004 (OS Build 19041.804)

I followed these steps but without success:
1. At the root of a non-system drive create a folder "folder".
2. Inside create a file "file.txt".
3. For folder add permission rule: everyone / deny / delete subfolders and files:



4. Pressing OK brings this warning:



5. For "file.txt" check effective access for current user -- it can delete:



Same happens if, just like with everyone, denial rules in "folder" security are further added for authenticated users and system.
Moreover, if the file owner is changed (to another user, happens to be admin) the current user (not admin) can delete the file. And this is of course reflected in effective access. Finally, trying the most restrictive measure -- adding the denial rule for the current user, regardless of the file owner, current user can still delete the file.
What am I missing? Does the system need restart?
What are the conditions for the contents of a folder to be protected from deletion and with respect to which accounts? Which accounts can / cannot delete in which circumstances?
