OmniDiskSweeper for Mac comes in a powerful little package and makes the cumbersome job of searching for large and unused files fast and easy. The application performs as intended and offers a rock-solid solution for anyone needing more free space on their Mac.
After an easy installation, OmniDiskSweeper for Mac presented us with a list of hard drives attached to our test machine, and we selected the internal 500GB drive. A new window appeared that populated with a list of folders and files, with their respective sizes listed right next to the name. The full sweep completed in under five minutes. The largest folders top the list with sizes color-coded: gigabytes in purple, megabytes in dark blue, and kilobytes in green. From there it was easy to drill down into each folder, zeroing in on the largest and most useless of files. In another five minutes we had freed up over 45GB of space. Remnant DMG files in our Downloads folder automatically saved, but unneeded Mail attachments, and old documents all unwittingly took up space. We were also able to identify another 25GB of files and folders that will need further scrutiny before we delete them for good.
OmniDiskSweeper for Mac significantly speeds up the process of digging through your hard drive and looking for unused and large files. This application is highly recommend for any Mac user, even for those who haven't yet approached the danger zone of limited free space.
OmniDiskSweeper is a great tool for making space on Mac OS X, Mac OS X Server and Mac OS 9 disks. When you start OmniDiskSweeper, it presents you with a list of disks attached to your machine. You double-click on one, and a new window opens with a browser listing every file and directory on that disk, sorted by size. This is very fast for HFS+ partitions: it takes about seven seconds to process one gigabyte. UFS partitions are significantly slower. Then you browse through the files and directories, and delete the large ones that you aren't using any more. The free space on the disk and the ordering of the directories are automatically recalculated. If you aren't sure what's in a file, you can double-click it or drag it onto an app on it to open it. It's that simple.
