Problems loading Packages

Hello, I tried to load packages in Dynamo without success. In the first instance I tried to “load packages” from Dynamo but a sign appears saying “the search has not returned any results” and then I try the “+” sign where it takes me to the floppy disks but nothing appears to load. It is common that three more folders appear inside the folders (bin, dyf and extra), which one should I load? How do I know which one is correct?
that could be happening?
Thank you

Which package and what version of Dynamo?
