How to load the existing qsys subsystem to a mew project IP catalog?

[Altera_Forum]

If I have several .qsys files which are the subsystem I built in previous project. Now I want to use them in the new project, how can I load them into new project Qsys IP catalog？ It seems if I put them in a directory, then I open one of them in Qsys, then all of them are loaded into the IP catalog. Is this the right approach? 

 Thanks in advance.

Qsys will find and add any .qsys file that it finds in your IP search path. By default this includes the current directory of the project. So when you open one, yes you'll see all of them pulled in.
