Are your files zips that use a custom file extension? If so, you can edit Beyond Compare's archive settings to make Beyond Compare expand them as folders.

To add a custom zip file extension to Beyond Compare 3:
Open Tools > Options.
Go to the Folder Views section.
In Archive associations, select Zip.
Add the mask for your files to the end of the semicolon separated list.
