Hi Vitor,

You should be able to do what you would like to do without going into the Laserfiche database. From the Laserfiche Administration Console you can set a time limit for content to be stored in the recycle bin. You'll find this under the Recycle Bin Settings.

With a time limit enabled on your recycle bin the system will automatically purge all entries that have been in there for the specified number of days. Using this setting should keep your recycle bin from getting too large.
