Just to be clear. Unless you have Desktop Persistence enabled under your SVW endpoint security policy, local HD files SHOULD be deleted at the end of a session, however, you seem to have found an inconsistency in respect to USB devices. The SVW policy allows you to control if access to removable drives is allowed or not. I always took that to mean that if you allow access to a removable USB drive then you accept that data could be transported away from the SVW session, this is the risk you take. I went away and did a set of tests with SVW desktop persistence disabled (SA IVE OS 6.0): Test 1: USB devices plugged in BEFORE SVW session started. SVW session initiated. File created in notepad and saved to 4 different devices: 1) Local C HD NTFS 2) USB HD fat32 3) USB stick fat 4) USB stick fat32. Exited session back to real desktop and checked where I saved the files: Results: Local C HD: - NTFS - File deleted USB HD: FAT32 - File deleted USB Stick: FAT - File NOT deleted USB Stick: FAT32 - File NOT deleted So it seems that my USB HD is treated like a local hard drive rather than a removable device. NOTE: This is further reinforced when I enabled desktop persistence and tried the test again with the file "appearing" to be on the USB HD between sessions, it seems the USB Hard drive is getting virtualised and not being treated as a removable device. Clearly there is an inconsistency in the way a USB stick drive is treated compared to a USB Hard drives. Both are removable USB drives so I would expect them to be handled in the same manner. What I don't know is which behaviour is correct. Should files on USB removable devices be destroyed or, as I suspect, should they remain on the removable device after the session ends? I will do a little more research internally and try to get you a more clear answer. Message Edited by ChristopherHowarth on 07-31-2008 06:31 AM
