# ls /media/sf_Transfer_Folder/'System Volume Information'
No printout. It is an empty folder

"System Volume Information" is one of those weird Microsoft hidden folders, that you would normally not get access to or even see in Windows. What's rather eclectic is that it's not a Windows OS:

Host - Ubuntu 22.04 desktop

Newly created Ubuntu 22.04 VM

Does Linux make "System Volume Information" folders too?

Meanwhile:

# ls /media/sf_Transfer_Folder/Wallpapers/

It looks like this folder is working?

I have no idea how that folder ("System Volume Information") was created ?

Can I delete "Transfer Folder" on Host and recreate "Transfer Folder" ? If YES please advise how to avoid mistake.

I can't view files on
-> File Manager -> sf_Transfer_Folder

I must on Terminal su -
then I can read their files on /media/sf_Transfer_Folder

It is quite strange to me

Did you make your guest OS user a member of the vboxsf group (and re-login afterwards)?

The System Volume Information folder gets created when a Windows guest accesses the Shared Folder.

Hi,

Thanks for your advice.

There are about 10 Linux guests and 5 Windows guests on this PC. All Linux guests use the same username and all Windows guests use the same username for Windows.

I haven't added the username of the newly created VM to vboxsf group because it is the same username. If I need to do it please advise how? Thanks.

Hi all,

Now I got it.

On each guest/VM I have to run following command on Terminal, disregarding all guests/VMs having the same username.

$ sudo adduser satimis vboxsf

Code: Select all

sudo] password for satimis: 
Adding user `satimis' to group `vboxsf' ...
Adding user satimis to group vboxsf
Done.

$ cat /etc/group | grep "vboxsf"

Code: Select all

vboxsf:x:999:satimis

The number "999" is different on each VM/guest

Now I can read on
File Manager -> sf_Transfer_Folder.

Lot of thanks for your advice.

Regards

Furthermore, pls guide me where to mark this posting as "SOLVED"? Sorry I forgot !
