how to open solid works file into solid edge?
Except what is described here u can always save your file as STEP/IGES and open it in another CAD software. however, in this manner, the CAD file won't be editable as the design tree would be unavailable.
Another thing to remember here is that once the file is opened, Solid Edge can easily edit the geometry without the design tree by using Synchronous Technology. This will allow you to use 3D driving dimensions, face relationships, direct edits etc to make the changes.
Also, there are some very good migration tools to batch convert SolidWorks parts, assemblies and drawings to Solid Edge. Complete with materials, assembly relationships, associative drawings and so on.
See here for an example:
