Selecting Files
Selecting files can be done manually or automatically. The files are highlighted to indicate that they are selected. The Statistics pane shows the number of selected files and the associated total diskspace.

Selecting files manually
You can manually select a square of files from the Identical Files matrix by clicking and dragging, or using the [shift] key.

Selecting files automatically
You can use one of four methods, by pressing the corresponding button:

1. Select All
The button Select All will select all double files. Use this option with care!

2. Select by Dir
The button Select by Dir will select the files which are located in the directories which are selected in the Directories pane. This option can be useful if you want to delete all double files from a specific directory.

3. Select Pattern
The button Select Pattern will select all files which abide a certain pattern. This option can be very useful if you want to delete all double files which belong to a series of files. With the buttons < and > you can make the pattern less or more stringent. The change in selection can be viewed live.

4. Select by Folder
This option is ideal to select newly added duplicate files. Suppose you have added new files to your system, e.g. in a folder:
C:\NewDownloads.

The next thing you want to do is to verify if there are any duplicates in this new folder. Select all the folders you want to check in the directories pane, e.g.:
C:\AllFiles
C:\NewDownloads

Now, just highlight C:\NewDownloads and hit the button [Select by Folder]. All the (new) duplicate files that are in C:\NewDownloads are now going to be selected and you can easily delete them all!

Option: leave at least one
The checkbox 'leave at least one' prevents the user from deleting all double files. This option is for instance very useful if you have two partial series of files, and want to keep at least one from either if they do not overlap completely.
