Anastasia comes with Elfinder preconfigured and tightly synchronized with the built in Assets Manager. This means the assets manager is aware of file uploads, removals,renames and more.
Each time you do something with your files in the file manager, the assets manager is notified and the database record for this file is also updated. The assets manager is able to store metadata and content so that it is easier for you to search or even use files inside your content. You can search your files by their filename, metadata or contents as soon as you upload them.
