There are situations where merging folders or comparing two or more folders is necessary. Teamviewer 9 mac license code. 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.

Disable “Self-scan”

If you disable self-scan for folder ‘VSD’ (as displayed in the image above), tells the application that it should not compare files inside it against each-other. As a result, it will compare the files inside it only with files that are located in other folders that are added to the folders list.

If you disable self-scan for the folders ‘VSD’ and ‘VSD1’, you tell the tool to compare the files in ‘VSD’ ONLY with the files in ‘VSD1’ and vice-versa. To clarify, that differs from the default setting which compares all the files in ‘VSD’ and ‘VSD1’ against each other.

As this feature is very versatile and works for more than two folders, it may be a little bit hard to understand. As some of our users have difficulties with how this feature works, we have provided more examples below.

Compare Folders for Duplicates – Examples

The [ ] brackets below visualize the check-boxes. The [x] inside the brackets denotes that the checkbox is ticked.

Scenario1:
Folders in the folder list:
[ ][ ]vsd
[ ][ ]vsd1
This is the default state. In this configuration, the application will compare all files in both folders against each other.

Scenario2:
Folders in the folder list:
[ ][x]vsd
[ ][ ]vsd1
Files inside ‘vsd’ will be compared only with the files in other folders – in this case ‘vsd1’. They will not be compared with each other. The files in ‘vsd1’ will be compared with the files in all other folders and they will be compared among each other too – which is the difference with ‘vsd’.

Scenario3:
Folders in the folder list:
[ ][x]vsd
[ ][x]vsd1
Files in ‘vsd’ will not be compared against each other. Likewise, those in ‘vsd1’ will not be compared against each other too. As a result, items in ‘vsd’ will be compared with the files in ‘vsd1’ and vice-versa. To summarize, if there were more folders in the list files in ‘vsd’ would be compared with those too. Also, files in ‘vsd1’ would be compared with them too.

Ticking ‘Disable self scan’ tells the application not to compare the items inside the corresponding folder with each-other.

You can disable Self-scan for a folder by ticking the checkbox in front of the corresponding folder name. Generally, there are two columns in front of the folder name column. To clarify, the column with the icon that illustrates a red circle with a white dash inside contains the “Disable self-scan” check-boxes. Of course, you can also hover the icon to view a descriptive tooltip.
