If you used the old VMware P2v or the newer Converter, then your VM should already be creatd and visible in the VIC, so you shouldn't need to browse any files.

Assuming your using Virtual Center 2.5, you'll need to make sure the Converter plugin is installe and enabled. After that, just right click on a the ESX host, and choose Import Machine. When prompted for the source machine, choose other, then click Next. You should now see a link for supported file types. If you click this, you'll see a list of supported file types.
