Regex seems overkill for this, but you can do it with a zero-width positive lookahead assertion[^]:
string s1 = @"c:\temp\lev1\lev2\lev3\MYWORD\lev5\lev6";
string mtch = "MYWORD";
 
string pattern = "^.*(?=" + Regex.Escape(mtch) + ")";
// == "^.*(?=MYWORD)"

Console.WriteLine(Regex.Match(s1, pattern).Value);



"These people looked deep within my soul and assigned me a number based on the order in which I joined."
- Homer
