There are situations where merging folders or comparing two or more folders is necessary. In such cases a “source” folder should not be checked for duplicates and should only be compared with one or more “target” folders. Comparing two or more folders for duplicates is very easy using the “Exclude From Self Scan” feature in the folders list.

Compare Folders For Duplicates

Disable “Self-scan”

If self-scan for folder ‘VSD’ is disabled (as displayed in the image above) the files inside that folder will not be compared against each-other – they will be compared only with files that are located inside the other folders that are added in the folders list..

If self-scan is disabled for the folders ‘VSD’ and ‘VSD1’ the files in ‘VSD’ will be compared with the files in ‘VSD1’ and vice-versa instead of comparing all the files in ‘VSD’ and ‘VSD1’ against each other.

Self-scan can be disabled for a folder by ticking the checkbox in front of the corresponding folder name. There are two columns in front of the folder name column. The column with the icon that illustrates a red circle with a white dash inside contains the “Disable self-scan” check-boxes.

    This is close, but doesn’t quite fix the (my) issue. After performing a large scan, I need to be able to select which sub folder to exclude from Autochecking. Often this isn’t the folder listed in the FOLDERS section because it is a sub folder. The proper place for this feature would be in the Advanced selection for Autocheck. The file names containing is close, but doesn’t include file path names. If it did, that would be sufficient.
