This might (or might not) work better: "\\.\\/\\w+(\\.txt)"

Indeed I was missing a backslash.

The following worked as I expected.

std::string expression("\.\/\\w+(\.txt)");

Actual not.  The first level of backslashes is processed by C++.  The regex library never sees them.  This pattern with match x/filename-txt, since . is a wild card.

Oh so it's just a case that it matches string "./File.txt". So basically I have to double backslash everytime? Thanks again, S.
