FreeSpace for Mac
Backing up your data to multiple storage locations is a very wise decision even though managing the additional drives can be time consuming.
FreeSpace is a minimalist status bar menu application that displays all the drives connected to your Mac, the available partitions or the network storage locations.
In addition, the FreeSpace app allows you to view the free space on each drive and enables you to quickly eject them one by one (press the arrow button assigned to each drive) or all at the same time (click on the “Eject All” entry in the menu or use the Command + E hotkey).
The application will organize the available storage location into logical groups, such as local storage, external storage, according to the device’s type and more.
On the right side of each entry, you can see the amount of free space. If the reading is in red, it means that the free space has dropped below the percent specified by the user in the Preferences menu.
FreeSpace comes with few customization options which can be accessed via the Preferences entry included in the main menu. You can choose to launch the application at login and you can decide what type of data you want to display in the menu bar: the icon or the free space of the currently select volume, how many decimal places should be used and if you want to see the measurement unit.
What's more, FreeSpace is able to send alerts within the application or via the Notifications Center each time you connect or eject a drive.
All in all, even though FreeSpace comes with quite basic functions, it can prove to be very useful if you are using a large collection of storage devices and you need to keep track of them.
