Overdisk enables you to visualize the ratio of file folders and their contents, allowing for you to quickly find where you may have too much data accumulated. This provides a way to find wasteful chunks of data that might be better off being archived or deleted altogether.
The days of paid zipped files have been long over since Microsoft acquired the rights to embed zipping into Windows, but 7z offers much more than just barebones .zip files. 7z is able to read/write virtually every zipped file extension, and does it much more efficiently and effectively than any other solution that you’ll find. Add to that open source development, and a much more robust user experience, and you have a clear winner in the realm of creating archives, zipping files, and compression ratios. Hail to the king.
