The 1.2 version of FolderOrg for Mac was available to download 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 actual developer of this free software for Mac is Doug Everly. The software lies within System Tools, more precisely File Managers.
From the developer:
FolderOrg is an AppleScript Folder Action that sorts files added to a folder by time-stamped sub-folders. Once attached, FolderOrg will organize new items added to the folder into a sub-folder named with the current date. This helps to keep track of when items were added to a folder.
