W10 Pro: Can't delete folder: "Is open in system"

Running out of disk space during editing of a family DVD (using Pinnacle
Studio 14) I found a large folder containing a huge redundant VIDEO_TS
disc image folder.

But attempts to delete it are met with "Is open in System"...

Tried rebooting - no difference, even though no app is runnning.

(Still Googling for problem, but system resisting attempts so far.

Suggestions very welcome!

Have you tried rebooting into Safe Mode, logging in as an Admin, and
deleting it from there?

You can also try "Taking ownership" of the folder and see if you can then
delete it.

When I went to the folder, I was greeted by *two* folders
with identical names. Neat... or what. The behavior is almost
like a Junction, but I haven't had the time to poke at it
with the Sysinternals junction program.

C:\Users\User Name\AppData\Local\Microsoft\Windows\Burn
Temporary Burn Folder
Temporary Burn Folder

Each folder has a desktop.ini and nothing else.

If I place a file in the folder, a notification pops up
in a minute or less, asking if I want to burn the new
file(s). Which of course, I don't want to do.

I do have a "Manage" option in the ribbon, but if you
change views and use some other option, the access to
Manage is lost. In any case, don't fret, as the "Delete"
button in "Manage" is grayed out, and doesn't work anyway.

*******

Instead, you can try this. In My Computer, right-click the
DvD drive, and there is a "Delete Temporary Files" item
in the menu. Whatever "Temporary Burn Folder" is under
consideration by the burn logic at the moment, will have
its contents erased. Since I have two burn folders, only
one got stripped down to its desktop.ini file. The other
still had its test file in it.

I can't guarantee that solves the "system" hook,
but at least it uses the services of Explorer and
some Shell Extension. Who knows, it might be NT Authority/SYSTEM.

DVDs are not hard drives, or floppies, or SSDs, or other rewritable
media where file changes are written atop existing clusters allocated to
a file. Spots on a disc are not reusable, only perhaps erasable. When
you update a file, you don't get to reuse those old spots on the disc.
Only if you used a rewriteable disc can you later erase them to use them
again. If you use a write-only disc, once you fill it up or there is
insufficient space for a new session with your updated file then you
copy off the last session from that disc, discard it, and burn a new
write-once disc.

Optical discs have sessions. Just because you no longer want a file and
delete it doesn't mean the disc space gets recovered. That session gets
the file flagged as unusable and the new file version shows up in a new
session. Every time you edit a file, you are flagging an old file in a
prior session, not physically deleting it.

If you are using rewritable discs, you can erase the disc to remove all
those old sessions and start will full disc space again; however, if
there are files you want to keep, you'll have to copy them elsewhere
before you erase the disc. Write-only discs will fill up with old
sessions until there is no more free space, and that's the end of
updating anything on that disc. Rewritable discs do the same thing but
when you choose you can erase the entire disc to start anew with it.

You said "DVD". You did not specify if you are using DVD-R or DVD-RW.

almost all discs are burned as a single burn (dao), without sessions,
and cannot be changed once burned. session-based burning was
notoriously unreliable.

Verbatim paste from notes I made years ago when having a similar
problem:

"For files or folders in general that report being in use and are not
therefore manipulable (this may look complicated, but after you've done
it once or twice, it will seem easy, I swear!):

1.) Download Process Explorer:

http://www.sysinternals.com/files/procexpnt.zip

2.) Unzip and run procexp.exe

3.) Click the View button and check "Show Processes From All Users".

4.) Click the right-hand binoculars (Find handle).

5.) Type the name or partial name of your file and search.

6.) Highlight each result and you will see its handle highlighted in the
lower pane.

7.) Right-click each handle in the lower pane and close it. Do not worry
about the warning if the file or folder is not system-critical.

8.) Close Process Explorer and delete the file.

Note: This will work on most but not all files since the handle may be
immediately reopened by a process."

Solved by booting in Safe Mode, using F6 to start in terminal session.
From there (without entering any commands!) I rebooted the system and it
then
allowed me to delete the file.

DVD production now almost complete.
