At this folder AllDup will extract files from archives or create files necessary for the file preview. All temporary files that have been created after the search for duplicate files was started will be automatically deleted after closing the search result.Exclude from scanning by Windows Defender
If you use Windows Defender as an active virus scanner under Windows 10/11, you can add file types or folders to its exclusion list and thus increase the speed of AllDup. The excluded file types and folders are then no longer checked by Windows Defender, which means that AllDup can examine this data more quickly and does not have to wait for each file until Windows Defender has completed its check.- We recommend that you exclude the storage location of the application data from AllDup so that there are no delays caused by Windows Defender when accessing the work data.
- If you always compare many image files, then you should exclude the different file types of the images or the entire folder that contains the image files.
