Manage any SQLite database on your computer.

Mozilla Archive Format, with MHT and Faithful Save от Christopher Ottley, Paolo Amadini

— Open web pages saved with Internet Explorer or other browsers (MHT)
— Save many tabs, video and audio reliably, in a single ZIP file (MAFF)
— Return to the original site you saved a page from, and more!

Примечание подборщика MAFF is more compact than a messy _files directory. MHTML is sometimes practical for emailing a site later. Only it should default to JPG etc when saving single files!

Примечание подборщика Be in control.
