Removes local thumbnails for preview cards.
|
|
|
|
The --days option specifies how old preview cards have to be before
|
|
they are removed. It defaults to 180 days. Since preview cards will
|
|
not be re-fetched unless the link is re-posted after 2 weeks from
|
|
last time, it is not recommended to delete preview cards within the
|
|
last 14 days.
|
|
|
|
With the --link option, only link-type preview cards will be deleted,
|
|
leaving video and photo cards untouched.
