Do Sandboxie contents get securely deleted?

[monstermash]

Does anyone know if when you delete your Sandboxie history, is it securely deleted? Is the data overwritten with random patterns like the free program Eraser does? Can this data be recovered later with any of the plentiful file recovery programs available? I would like the data to be overwritten, not just deleted, does Sandboxie do this? Thanks for any help.

I've never seen info that states Sandboxie does secure delete.

Once Sandboxie empties the sandbox that becomes free space, use Eraser to wipe free space and all is well.

Of coarse on a large HD with lots of free space this could take awhile

I'd also like secure deletion to be made a feature of Sandboxie. Just 2 or 3 passes would be better than not at all. How about it Tzuk?

Instead of trying to get the author to incorporate secure deletion into the program, which could take some time, how about just telling us exactly which things we need to delete with Eraser ( http://www.heidi.ie/eraser/ ), since that can already do secure overwrites.

Tzuk, can you tell us what we need to delete with Eraser, so we can do secure deletion (as many overwrites as we want) of the Sandboxie history?

Thanks very much for any assistance.

Delete Contents of Sandbox does only two things, delete files and registry keys.

The files are located below the sandbox top level folder, by default:
%APPDATA%\Sandbox. You can tell your secure eraser to start erasing there.

The "retain auto-complete information" means the Data\PStore.dat file is not deleted.

The registry keys are located below HKCU\Sandbox, and they are always empty and volatile. Volatile means they vaporize the next time the computer restarts.

Hi, Sandboxie works well and I've had no problems with operation. However, on the subject of deleting sandboxed files, there is a question about how file sizes are reported (W-Explorer & Eraser). Certain temporary internet files, particularly 3x1 gifs, are reported at 1.46GB in both apps. Not a problem ordinarily but erasing these files takes much longer than it would if file size was reported accurately. This only happens to sandboxed files and non-sandboxed TIFs are reported as normal. Top level folder is E:\Sandbox and same thing happens under TLF default.
Any ideas?

Here's a test 3x1 gif i uploaded to imageshack



The following sizes are what I get when I view the temporary file in the sandboxed IE folder.

Size: 43 bytes (43 bytes)
Size on disk: 4.00 KB (4,096 bytes)

p.s. my OS is Win2K SP4

Hi, thanks for the reply. After posting yesterday, I decided to have another look at this. I restored a partition image dated prior to the Sandboxie installation and, lo and behold, after a new install of SB the problem disappeared. Without spending too much time on this, I'm assuming a registry entry was the culprit. Once again, thanks for your time.

I have added "C:\Documents and Settings\USERNAME\Application Data\Sandbox" to Ccleaners custom folders cleaning which can now do a secure deletion.

1,3 or 7 passes.

Or if you want to keep regdata and pstore use this -

"C:\Documents and Settings\USERNAME\Application Data\Sandbox\DefaultBox\Device'

After a major cleanup I usually open FF outside the sandbox and login to all my forums and set Ccleaner not to clean FF so as my info is retained when I first run FF sandboxed.
