Hi, I have BufferZone (Sorta Like Sandboxie,)
Can Avast’s Sandbox Collide With BufferZone?

BufferZone is better than Avast Sandbox.
Because Avast Sandbox have no virtual environment to open USB pendrives and others, also whole hard disk. It’s only handle .exe/applications.

What’s the problem on sandboxing only the suspicious files?
Not any file in pendrives should be blocked… clean files for instance…
