vxe is a multiple document interface application. vxe can be used to open and edit multiple files at the same time. Just imaging openning 20 or more files with vi, you will be convinced of the space saving benefits of MDI interface. The maximum number of files opened so far with vxe is 600 files. Unlike the buffer switching of xemacs, vxe is doing window switching since each file is displayed in its own child window. The benefits of window switching is the user can view multiple files at the same time. This is very helpful for copy and paste, or drag and drop operations. Navigating is easy. Simply double-click on the file name of the file view list, the child window will be popped up to the front.
