How do I delete a folder that can't be deleted normal way?

Question

I was working on my code and tried to run a migration against a my local database. Migration couldn't be applied but this folder was created:

Soon after, my whole solution couldn't be loaded and I cannot still delete this folder. What do I do? Where did it come from?

I tried the following:

1) Reboot

2) Safe boot

3) Open CMD with administrator rights and run rmdir "'.." but that gives me an error stating that such path doesn't exist

Answer 1

I got past similar stuff with:

cd \just\above\the\problem\folder

rem dir should show the problem folder name

rmdir /s /q "problem folder"

Try to use Unlocker Program.

You can download at :

After you install the program:
1. Open the program.
2. The Browse File or Folder Window will be shown. Locate this to your undeletable folder. Then click OK.
Browse File or Folder Window

3. On the action selection, select Delete and press OK.

The solution is to "cd" into the folder's grandparent and recursively delete the parent folder by running rmdir <folder> /s /q.
