Download of FolderInfoX 1.0.0 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. This Mac app was originally developed by Tomoyuki Okawa. The program lies within System Tools, more precisely File Managers.
From the developer:
FolderInfoX allows the user to reposition and resize any number of folder windows. If you want to monitor the position and the dimensions of a particular folder window, use Info and just drag and drop a folder onto application's drop box. Execute a specified position and dimensions on any number of folders.
You may want to check out more software for Mac, such as eps2pdf, Little Disc+ 3 Trial or Files Renamer, which might be related to FolderInfoX.
