There are four window views supported;
For file management, the Text and Details views are superior because they are faster, display more files in the same window area and consume less resources.
To instantanously display the maximum number of files in a window, Text mode is the clear winner. The Data Panel is designed to show the data of the the cursored file. This view is recommended is you do not need to compare the columnar data of the Details view.
The Details view is often preferred because it is similar to many older file managers and presents file data for each file. However, the number of files instantanously viewable is typically less than one-third of the Text view.
The Icon and Name views consume memory for the icons and loading time is definitely degraded although FS/2 loads the icons on a background thread after the files are scanned. The number of files viewable in the typical display is about the same as Details view.
