Hi,
I've got an folder path (dirID, vRefNum) of an folder.


You don't really have a path. The string you want is the path.

Now I want to convert this path to an String. Is there an function that could make this for me?


Not directly. You'll need to get an FSRef as an intermediate step.

OSErr DirIDToFSRef( FSVolumeRefNum vRefNum, UInt32 dirID, FSRef &outRef ) { FSRefParam refParm = { 0 }; refParm.ioVRefNum = vRefNum; refParm.ioDirID = dirID; refParm.newRef = &outRef; // refParm.textEncodingHint = kTextEncodingUnknown;

	return PBMakeFSRefSync( &refParm );
}

Then you can get a path using FSRefMakePath or you can use CFURLs.

After I've got the path as an String I want to change the String and convert him back as an dirID, vRefNum if there is any function with that I can do that.

You'll need to go back through an FSRef. See Files.h and FSGetCatalogInfo.
