The current DAZStudio 4.9 content folder is called My DAZ 3D Library, My library is the hold over from DAZStudio 4.8 which makes it that much more confusing when installing older, non-Daz content files. Content folder is actually the top most folder found within DAZ compressed files, individuals manually decompressing these files have, inadvertently, retained this hierarchy thinking that this is the true arrangement of folders. If you use DAZ Install Manager (DIM) to install DAZ zipped content, the Content folder is discarded and everything folder within is moved to their appropriate location either to My Library or My DAZ 3D Library, whichever you are currently using.
