Source Folders

Source Folder List

In the source folder list, you can specify which drives and folders to scan for duplicate files. You enable a source folder for searching by checking the box in front of the folder path.

Exclude Subfolders
If you clear the checkbox in the Search all subfolders column for a source folder, then all subfolders in this source folder will be excluded from the search.

File Protection

Add new source folder
You can add a new folder to the source folder list by clicking the Source Folder button in the toolbar, by right-clicking in the source folder list, by clicking the + button in the top right corner of the source folder list or drag and drop a folder from Windows Explorer into the source folder list.

If you right-click on a source folder, you will see a menu with various commands, such as Edit, Delete, Open, ...

Comparison Methods

Compare files from all source folders
With this comparison method, the files from all source folders are compared with each other.

This comparison method does not compare files that are in different source folders.
Example:
1. Source Folder: C:\Data
2. Source Folder: D:\Server
Files:
1. C:\Data\Work\info.txt
2. C:\Data\Home\info.txt
3. D:\Server\Work\info.txt

Options

Don't search folders (NTFS junction points) that point to the contents of another folder
NTFS junction points are empty folders that point to the contents of another folder. This option enables you to prevent these folders from being searched and processed. This option is activated by default. When deactivating this option you should check first that no loops are created by the junction points and no data items are processed twice.

Disable Windows 64-bit file system redirection
This option enables AllDup to determine the correct count of all system files on a 64-bit Windows system.
