Probably not a whole lot unless...
IF the subdirectories were to be on a given higher level path branch, then one could probably get the desired result directly via a shell dir() command with the suitable wild card. Would depend on the shell for specific switches, of course, as well as the above condition. On Winders CMD.EXE, the following seems to work...
[~,dirs]=dos(['dir /s /a:d /b *' strToFind '*'];
Whether it would be faster/better would likely be in the eye of the beholder and how high up in a location would have to be to cover the whole chain desired. Of course, one will need to ensure the starting path is where it needs must be in the running shell so likely need to create a batch file that takes care of that detail and dispatch it instead...
I haven't ever understood why there isn't an extension to a cellstr of strfind that "just works"; doesn't seem that big a deal.
