Using Sandbox - where to run the executionable from?

So guys, I'm planning to use this thing for the first time. I've downloaded some shady indie game distributed for free that could well possibly contain malware so I'd rather play it in Sandbox.
Now here comes the matter - my hard drive is divided into two partitions (C:\ and D:\) and as normally I've downloaded the piece of software to D, but that partition isn't shown in the File Explorer of Sandbox. So I guess I shall move it to C, but I wonder is that what I'm actually supposed to do - I mean, how is the system drive safer than the storage one, why is only C displayed in Sandbox and do I need to move the software to be tested to a more specific location?
I've seen in some tutorials guys are running the exe file from Sandbox Desktop but it would be quite a pain to copy-paste 2GB every day to it. Is it safe to move it once to C:\ and run it from there every time?

Well, I've found the answer on my own. Turns out the "C:" in Sandbox does not mirror the one of the host environment - none of the additional software and user files I have on it are shown there. Which makes my question pointless, I obviously can't get around copy-pasting the software every single time...

You can setup a shared folder with host and run file inside sandbox.

I haven't tried sandbox for ages but I might give it another go.

I had an issue that if you were playing around with apps that needed a re-boot etc after install, or configuration change / update could you preserve the status of Sandbox across re-boots rather like "check-pointing".

I'm not sure if this question was answered but there have been zillions of updates to W10 and W11 since then so the answer might be different.

For me if the "space" can't be preserved across a re-boot then it's not especially usable as I can test with several complete Windows systems from vhdx files which can easily be re-copied again. To restore a vhdx file only takes minutes these days. I I agree that one doesn't always want or need to use full VM's for testing (although as in all these things it depends on what your objectives are).

Insider versions of sandbox now persist across reboot.
