Most apps are removed by simply putting them into the Trash. In that case all of the service files remain on the disk, littering your Mac. Such broken service files are unnecessary and they just take up your disk memory. These files are called Remains.
App Cleaner allows you to find such “forgotten” files and clear them. Just launch App Cleaner and it will do all the work – find all the apps on your Mac with service files, as well as Remains – the forgotten files.
Click the Remains panel (“R”) to view them. You can also use menu command View->Remains or the CMD+2 shortcut.
There are file names of application’s files sets in the left column. Because the app has been deleted, there is no way to know their names. So, these files are named as the apps had created them.
If you select one of the elements from this list you will see all related files remaining from the removed application in the right column. Delete the Remains by selecting the needed files and clicking the Remove button in the right corner.
*Note that some apps can create and save their service files in different folders, even when it contradicts Apple’s requirements for the organization of temporary and service files . In this way, these files can be found by App Cleaner as well and be displayed as Remains, though in reality these files are used by applications.
Please, make sure you don’t need these files when removing the Remains. Deleting certain files without removing the app can cause malfunctions.
