This happens every time I open a .pdf of a USB flash drive

Copy that file to hard disk and then open it from there.
What happens?

It doesn’t get sand boxed, the .pdf files opened from the hard drive open normally. The same files when opened from the USb device are sand boxed.

That means USB device is untrusted by default. :wink:

You can add it to the Exclusions list and it won’t get sandboxed again.

Actually, you can’t exclude anything from external media. It will always be considered untrusted.

so all file inside a external device are sandboxed. is there an actual need to sandbox .pdf files, I mean should sandbox act only on programs?

Thank you for your issue report in the required format.
