DOSSHELL was a GUI file manager released with MS-DOS version 5.0 in 1992. It was designed as a graphical alternative to command.com. This computer program allowed users to easily see a disk's entire directory structure, and programs could be run by simply double-clicking the filename with a mouse.
DOSSHELL fell into disuse due to several factors:
- DOSSHELL was incapable of multitasking. It could only switch between programs running in memory, and even then the system would still take a significant performance hit. And all the running programs would have to fit into conventional memory.
- Microsoft Windows 3.1, released the same year as DOS 5.0, was much more popular among users than DOSSHELL. Windows was capable of multitasking, was more stable, possessed a more pleasing interface, system performance was much higher, and had complete access to the system's RAM.
DOSSHELL was discontinued after the release of DOS 6.0, and was incompatible with the versions of DOS shipped with the Windows 9x line.
