Symantec File Share Encryption may require a significant amount of time to complete Encryption\Decryption routines for larger folders. Some routines may not provide user feedback to indicate a process is still running successfully.
Symantec File Share Encryption folder verification has been improved in version 10.4 MP1. Previously, a folder of 100GBs would take roughly 20 minutes to process, with no indication that the operation would take time. Symantec File Share Encryption now displays a note in the UI upon clicking "Folder Status", which says "File Share Encryption is scanning this folder....", and has been improved many times over. A folder that used to take 20 minutes to verify, could now take 2-3 minutes with File Share Encryption 10.4 MP1.
