Failed opening ...

[marius_1956]

When launching VirtualBox I get messages related to an error while opening a support with a given ID because the related path is not fully qualified.
The message is in Italian.
The exit code is VBOX_E_FILE_ERROR
How can I traoubleshoot the problem and detect if a VM is corrupted (I have a lot of VMs).

The message is in Italian.

If the message text is posted (Use the Copy button if there is one) it can be translated.

Please post the text, and also the guest's .vbox file that caused the error:
Please right-click the guest in the main Virtualbox window's guest list, choose "Show in Explorer/Finder/File Manager". In the window that opens, zip the guest's .vbox file, and post the zip file, using the forum's Upload Attachment tab.

Many thanks for the answer.
I include the text of one of the messages I get:

Apertura non riuscita del supporto con il seguente ID: {95e87c47-ce0a-492e-8413-e8263731c117}.
The given path '{95e87c47-ce0a-492e-8413-e8263731c117}' is not fully qualified.
Codice di uscita:VBOX_E_FILE_ERROR (0x80BB0004)
Componente: MediumWrap
Interfaccia: IMedium {ad47ad09-787b-44ab-b343-a082a3f2dfb1}
Chiamante: IVirtualBox {d0a0163f-e254-4e5b-a1f2-011cf991c38d}
RC chiamante: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)

VMs look to work fine.
Maybe the proberm can be due to some VMs I deleted without removing them from the list?
I left them on the list in order to find them if I restore them from backup...

That error is saying that a particular file is being accessed, but the data has a UUID instead of a drive & folder path. Post the .vbox file for the guest that has this error, and we can see what can be done.

[marius_1956]

I can't identify the guest causing the error.
How can I?
I removed from the interface the VMs I had previously deleted, but the messages are still displayied.
The last VM cannot be deleted, and the messages are still displayied.
How can I troubleshoot the problem?

If you could tell us what you did, it would help us diagnose it better. (haven't time to watch a youtube video myself)

You could try zipping & posting the 'C:\Users\{you}\.Virtualbox' folder (note the period in the folder name.)
