Fiwi is a compact, faceless application to help with moving files and folders via 2 symmetrical Finder windows. It really helps saving time and avoid confusion.
Retina Screens users: We have had reports that Fiwi is not able to manage Finder windows as expected when run on a retina screen. As a temporary fix please use the Fiwi set up app provided. In the Finder please set up the two windows exactly as you wish them to appear, run Fiwi set up and choose Windows Settings. In the ensuing dialog box choose Set Customised Windows. Fiwi will maintain those settings correctly. To change size or orientation please use Fiwi set up again.
Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
Note: Although Finder indicates that this is version 1.0, the developer states that this is version 2.0.9.
