Is there a way to write the folder name (or other names) as a regular expression

[brushington]

I want to block the whole D:\ except a very detailed folder such as D:\a\b\c... It is very difficult for me to add every folder in D: in Sandboxie, because it is too many folders and files. So is there a way to add it simply such as write a regular expression in the Sandboxie setting? Thank you.

Generically speaking, no. While it is possible to isolate areas and only allow 'certain' things to see or interact with them - there is nothing atm, to my knowledge, which works exactly as you desire. I could easily use that scenario myself but sadly it is not how things are in the cards, atm. The workarounds I tend to use are GLOBAL [ClosedFilePath(s)] with an [!]exception for whatever program.exe or <ProcessGroup> actually needs access followed by any other relevant rules that may help lock that particular box down inside its own.
Sort of a deny everything except this and this extra rules for related boxes which might require many other rules of their own.

ugh so confusing!?
