When developing a website with WordPress, one of important thing you need to consider before you start to upload tonne of media files to your media library is how to organise your media files. At the early stage after WordPress installation it may not seems any issue, but in long run you will realise how bad is WordPress in organising media files that have been uploaded. Its a total failure since WordPress Media Library does not have any media library manager or even basic folder function that should come natively with the cms.
One of the most popular plugins to solve this issue is Filebird. Filebird come in free and commercial version is a plugin to organise all files in media library. It is very easy to use, you can create, delete, search and rename folders. Its also support drag and drop, bulk process, and many more. I hope this features will be added to WordPress in future.
