In this regard, SheepShaver and Basilisk II function exactly the same.
You can use the My Computer option, or just have a disk image that can be opened in both SheepShaver and HFV Explorer.
From the SS Windows manual:

When the hard file is created, the GUI will return to the “Volumes” tab, and the hard file should be listed as added to your emulated Mac. While it is not necessary for the purposes of this guide, you can check the “Enable 'My Computer'…” box to gain access to files on your PC from within the emulator. This is an easy way to copy downloaded programs to the emulated system. See figure two.
