Windows 10: 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?

Directory Size Utility

First of all nice utility, Mindweaver!
Second of all, it's so nice to see that this section ain't dead.

I have a few questions/suggestions, maybe you'd want to see ...

• maybe you rename Get Folder button caption to something more intuitive? Add Folder, Get Folder Size, Check Folder Size or something like that?
  
• Could you add subfolder files to the right pane? (it can be a tickbox with include sub dirs)
  
• maybe you also add export list to excel?
  
• there's delete file button maybe you add delete folder button too?
  
• and finally maybe you can add UP button for directories?

 

Directory Size Utility

Thanks buddy! Yea, this section's not dead. Kreij and I have big plans for this section. I don't want to give nothing away, but we have some bigger projects down the road. *Toast :toast: I feel I'm pretty good at coding with different languages, but I'm well behind Kreij's level of experience with those other Languages. I've been working on those other languages, and soon I'll feel comfortable enough to start, and not feel like I'm holding the project back. *Toast :toast:

Now on to your suggestions.

• maybe you rename Get Folder button caption to something more intuitive? Add Folder, Get Folder Size, Check Folder Size or something like that? Yea, that's been bothering me and I like your suggestion "Add Folder". I'll change it on the next release.
  
• Could you add subfolder files to the right pane? (it can be a tickbox with include sub dirs) I could add this, but let me see if I understand what you're asking. By subfolders you mean add all the folders in the left panel to the right panel? Those folders are all the subfolders in the "Get folder".
  
• maybe you also add export list to excel? I'll add this on the next release.
  
• there's delete file button maybe you add delete folder button too? I'll add this on the next release.
  
• and finally maybe you can add UP button for directories? I'll add this on the next release.

These are all great suggestions! Thanks Drone! *Toast :toast:
