Ways to close and delete corrupted file

They may not be accessible because they may be in use by the system or some background program.

Go into Safe Mode and try to delete that way (most of the time you can delete them in safe mode).

But before you do, make sure these folders are actually corrupted, that they are not actually protected system folders that will cause problems if you delete them.

You should first Google their name and see if any info comes up about them being important system files.

If not important, to get into safe mode in most computers, restart the computer and press the F8 key repeatedly while it is booting up (the computer will probably start beeping after a while -- just keep pressing till the safe mode screen comes up).

A screen will come up giving you various options -- select "Safe Mode" and when it is done booting up into safe mode, close the windows explaining what safe mode is and then, try to delete the files.

Before doing this, you may want to try opening the task manager (press Ctrl+Alt+Delete keys at the same time and then click "Start task manager") and select the Applications tab.

This will show you all the running applications on your computer -- one of these may be keeping the files from being deleted.

You can then shut down any applications you are not using by highlighting each one and pressing "End Task" for each.

Once all are closed, close the Task Manager and try deleting the files.

If no luck, then try deleting them in Safe Mode as above.
