Sure, while operating on OS X applications could be installed and have been deleted before the first launch of App Uninstaller.
Frequently applications are removed by a simple dragging of the application file to the Trash. At the same time, all supporting and temporary files remain on the disk and clutter the system.
It’s obvious such files are no longer needed and simply take up your disk space. We call such files Remains.
How to find and delete Remains
Application Uninstaller provides a possibility to find and review such “forgotten” files and delete them. Right after being launched, App Uninstaller finds all programs and related files, as well as Remains – forgotten files.
Choose view mode “Remains” to see them. To do this click on Remains panel, use menu command View->Remains, else CMD+2 shortcut.
The list on the left contains file names of application’s files sets. Since the application has been removed and there is no way to know its name is taken as a name of one of its files left on the drive.
By selecting one of the elements in the left table you can see all related files remaining from the deleted application. To delete Remains, you need to select the files of interest and click Remove.
* Some applications create and write their temporary files in different folders, violating Apple requirements on the organization of temporary and service files. In this case, these files can be found by App Uninstaller and displayed as Remains too. Although in reality these files are used by applications.
Please be careful when removing Remains, as the removal of certain files without removing the app can lead to malfunctioning.
