Clean up unused and hidden content

Hi,

In order to export the text content of a module for a translation, i need to delete all the hidden content remaining from older versions, duplicated slides or imported content from other courses. (during the process, i prefer to hide object rather than delete them, in case i need them back for some reason)

So i'm wondering if it exist an option to automatically clean the module?

for instance:

- deleting all hidden objects on slides,

- delete unused masters,

- delete slides and layers wich are not linked by any trigger set to show them,

- etc.

 

Thanks
