What happened to "stringDirectory"?

I was using stringDirectory to load the path of a folder to load samples.
while porting to V1 I have an error while compiling

std::string dir=stringDirectory(DrumSampler0->lastGlobalPath);

results in:

error: use of undeclared identifier 'stringDirectory’

OK, i think I found out

replaced by rack::string::directory
