from Wikipedia, the free encyclopedia

Calmira is an open source Windows 95 -like desktop environment for Windows (for Workgroups) 3.1x and for Windows NT 3.1 / 3.5x (Server).


While Windows 95 was being marketed, efforts were made to equip Windows 3.x with a modern user interface. In 1997 the first version of Calmira appeared. Like its start menu, this program is similar to the Windows 95 user interface. It is managed entirely via initialization files (instead of entries in the system registry ); most settings can be accessed directly via the Settings options . Calmira does not need to be installed, just a start entry in the "SYSTEM.INI" file in the system directory. When you start it for the first time, it imports the program groups and settings from the program manager if you wish. However, it can also be used in parallel with the program manager for test purposes without system integration.

Calmira can be further developed and translated with Delphi 1.0, it remains free.


Development began when the source code was first released in February 1997. In November 1998, it was renamed Calmira Online II.
The current version of Calmira is Calmira LFN 3.3, which, unlike earlier versions, now offers support (in the Calmira Explorer ) for long file names.
Calmira was and is still very popular with Windows 3.1x users.
