You can delete all the preview clips from your entire collection in one go.

If you are not sure what you are doing don't follow this. I take no responsibility for you accidently deleting your entire collection...you have been warned!

Goto the "my collection" tab
Make sure you can see all of your cards(you haven't hidden any)
press CTRL and A to select all the cards
in the top left you will see a bin icon
right click the bin
select "delete previews only" AS I SAY, YOU HAVE BEEN WARNED!!!
a dialog will open asking you to confirm deletion of the previews.

upon confirmation istripper will appear to stall, just be patient and don't close istripper and it will come back to life once it has deleted the previews.

for me with 2113 active cards this saved me ~50GB of space.

Nice tip. But are these preview clips of already installed cards or the previews of unbought cards?

Yes 50GB sounds like a lot.. Till you do a bit of math...

50GB / 2113 cards is a mere 23.67 MB per card.

and with a 1TB HD it's a small percentage of Storage. ( 5%)

But in terms of Full Cards,
50GB might be room for about 90 cards.

The Method describe above are Previews of Bought Cards ONLY.

un-Bought Previews are not Affected by the above described procedure.

I prefer to keep the previews.
In many Cards the Preview clips are Unique Short clips, and are also the ONLY non-Nude clips for the card.

Yes, Some Previews are just and Edited version of a Longer clip, but most are Unique.

Deleting them, Might prevent you from being able to watch a No Nudity level show.

Thanks, this is what I wanted to know. I prefer keeping the previews of bought cards.
