FileManager Sort
The FileManager provides an inbuilt Sort functionality that allows you to sort the files and folders in the current folder. The main options are Ascending and Descending.
The dropdown in the toolbar exposes several more options to sort by:
- Name
- Type (extension)
- File Size
- Date Created
- Date Modified
Choose a Sort option from the toolbar dropdown.
