You can find Linkgrabber Filters and Views under Settings -> Linkgrabber Filter
Filters and Views looks pretty much the same, what's the difference between them?
Filters can be used to 'permanently' filter stuff you do not want.
When links are filtered, they will not be displayed in the linkgrabber at all.
In the bottom section of the linkgrabber, a button named "Restore X filtered links" will appear that can be used to restore items that got filtered.
Views will create checkboxes on the right side in the linkgrabber that can be enabled/disabled to hide show/hide affected items.
If in doubt, create Views and not Filters.
In this article, the word "filter" may be used for both filters and views since the conditions you can select for them are pretty much the same.
Some filter conditions support wildcards and also regular expressions ("regex") via the checkbox on the right side.
Only use regex if you know what you're doing!
Test your regex either by doing rightclick into the field -> "Test XY expression" or use free webtools like regex101.com.
Typical use cases / what you can do with filters/views:
Filters and extra settings:
If you do not want the ability to restore filtered links, you can disable it in the advanced settings via LinkgrabberSettings.restorebuttonenabled
Views and extra settings:
By default, selecting a view selects all affected links.
If you do not want this, you can disable it in the advanced settings via LinkgrabberSettings.quickviewselectionenabled
I want to filter links with/without a specific file type or file name but my filter does not seem to work, what can I do?
Some information may only be available once the links are checked.
For optimization reasons, filters will work as fast as possible and, whenever it looks to be possible, filters will work without a link-check.
In some cases, this can lead to filters not working as expected.
Enable the condition "File -> is -> Online" and try again.
