Opening a large IGS model

I have a rather large IGS file (261mb) of an assembly with 100s of parts.  It was originally created with Solidworks and exported to IGS before we received it.  Now when I open it, it processes and creates every single part file (I have to click the Part template and click OK for every file).  This could take days.  How else can I open this file?

Thanks,

Brandon
