Download of OpenFinder 1.1.0 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The software lies within System Tools, more precisely File Managers. The actual developer of this free software for Mac is Kalle Persson.
From the developer:
OpenFinder Provides a command for opening Finder in the current directory. When installed, provides the “Finder: Open here” command, which opens Finder in the current file's folder, much like The Sublime Terminal plugin. After unziping, rename it to “Sublime-Finder” or something so you can use it.
You may want to check out more Mac applications, such as eps2pdf, Little Disc+ 3 Trial or Files Renamer, which might be similar to OpenFinder.
