Files and folders protected by File Share Encryption should show a padlock overlay in Windows File Explorer:
Sometimes the padlock overlay icon is missing or it is shown intermittently.
This issue may occur only on network shares. You can confirm this by creating a protected folder on a local drive and checking that the issue still occurs.
Symantec File Share Encryption 10.5 and above.
Check if the file/folder is actually encrypted by doing the following:
Right click on PGP Tray from the notifications area of the taskbar and choose Options or open Encryption Desktop and choose Tools / Options from the menu. Check in the File Share tab that the Overlay PGP icon on secured files and folders option is enabled:
From Windows File Explorer, navigate in and out of the protected folder or simply try waiting a few minutes.
Ensure that you are running the latest version of Symantec File Share Encryption.
The other method is to do a "--list" command on the share via the command line with pgpnetshare.exe:
pgpnetshare.exe --list "folder path here"
This will show you all the users and roles, so you can use the pgpnetshare.exe binary to check on all of these attributes.
When the shares themselves are massive, it does take Windows time to render the overlay icon.
Also, the icon size can also affect if this is showing up or not...if you change to "Details" or tinker a little bit with the sizing of the folders:
