During the discovery process, you may want to exclude certain system folders, file types, files with certain prefixes, etc. from the index - regardless of which discovery location the item may be found in. The "Exclude List" is a global list of things Voyager will skip when indexing.
For example, you may want to ensure that items within the "C:\Windows" folder are never indexed by Voyager. To do this, click "Exclude List", then "Add". A dialog is displayed allowing you to configure what to exclude.

To exclude the "C:\Windows" folder, select "Folder" from the dropdown menu and choose "C:\WINDOWS" from the list. Click "Exclude", and the folder you selected will be added to the Exclude List.

To remove the location from the Exclude List, click the '\[x\]' and the folder will no longer be excluded from the discovery process.
In addition to excluding system folders, you can exclude items based on wildcards, or regular expressions (regex). For example, if you want to exclude everything with the prefix "test_" from the index, select the Wildcard option and enter "test_*" as the Pattern.
