You can create a collection of files from either from the eXplore view or from the detail asset view.

From eXplore view: Click ”Bulk actions”. Select the files you want to add to the collection and then click ”Add to collection”.  Tip: filter on files first to hide the collections.

From details view: Click ”Collection”, then ”Add to new collection”.

In both cases a ”Create collection” window pops up - fill it with the name of the collection, tags and description and choose a thumbnail for the collection. Then click ”Create”. Click “View collection” to display the collection.
