Patience Pays Off
Plenty of computer enthusiasts are well aware of the use of JDev files to get the information that they need to be transferred around wherever they want it to go. That said, there are not as many people aware of the fact that the initial upload process on JDev files to the Netbeans can take a considerable amount of time.
It is true that this is how the system works, but don't let that get you discouraged from using it. There is still a lot of upside to getting your JDev files onto Netbeans once you have done so.
