Microsoft Windows 3.x logo driver

Files with lgo file extension can be usually encountered as various logos, for example the ones from Microsoft Windows 3.x operating system.
Found 5 different file type records with the same lgo filename suffix.

The lgo file extension is associated with the Microsoft Windows 3.x family of graphical environments for MS-DOS operating system (Windows 3.x is not separate operating system).
It appears that .lgo file stores boot logo of Windows in bitmap picture file format.
Some graphics editors may be able to edit these files, much like any other pictures.
Possibly can be converted to other graphics formats.

Modern ListGeo uses the LGO file extension for files that contain output from a ListGeo operation. The file belongs to the Modern ListGeo software rather than representing a general-purpose image or geospatial interchange format.
The contents depend on the operation that created the file and are intended for use with Modern ListGeo. LGO files should therefore be kept with the related project or source data when the output needs to be reviewed later.
Open an LGO file with Modern ListGeo, the software that creates this format. Use the program's open or import command and select the file.
If Modern ListGeo is unavailable, a text editor may be able to display the contents, but it may not present the output in the form intended by the program.
LGO files are program output rather than a common exchange format, so there may be no direct conversion utility. Open the file in Modern ListGeo and use the program's available export or save options, if provided.
If the file is readable as text, its contents can be copied into a suitable document or text format, but this may not preserve any program-specific information.

MSWLogo is a Logo programming environment for Microsoft Windows, commonly used for programming education. It lets users write Logo commands and procedures and create programs that control the Logo drawing environment.
The lgo file stores the saved Logo program design, allowing the work to be reopened and continued in MSWLogo.
The format is intended for Microsoft Windows.
Install MSWLogo on Microsoft Windows and use its Open command to open the lgo file. The file should be opened in MSWLogo so that its Logo program can be loaded into the development environment.
To use the program with another Logo implementation, open the lgo file in MSWLogo, copy its Logo procedures and commands, and adapt them to the other implementation before saving them in its supported format.

The lgo file extension is associated with the OS/2 operating system developed by IBM.
The OS/2 Boot Logo format is used under OS/2 Warp versions 3 and 4 for storing the boot logo. The boot logo is the image that is shown at first when OS/2 starts up after a re-boot.
Under Warp 3, the size of the boot logo image is 640x400 pixels. The VGA resolution used at boot time is 640x480.
Warp 3 reserves 80 lines at the bottom of the screen for showing copyright information. This space cannot be used and thus the size of the boot logo must be 640x400. (Using a 640x480 boot logo under Warp 3 will result in an OS/2 TRAP at system startup.) Warp 4 does not reserve this space and a full-screen 640x480 boot logo may be used under Warp 4. The boot logo file is located on the root of the OS/2 boot drive. The name of the file is OS2LOGO and by default the file has the system attributes hidden, system, and read-only set. The default extension is LGO.
Use PMView Pro to view *.lgo OS/2 boot logo file.
Probably can be converted to other formats.

The U.S. Geological Survey (USGS) Digital Line Graph format stores digital vector data for cartographic features. It can represent topographic and planimetric map information.
DLG data is derived from aerial photographs or cartographic source materials by using manual and automated digitizing methods. A file can therefore contain mapped line and related feature data rather than a raster image of a map.
MapViewer on Microsoft Windows can open this type of file. The format is a legacy USGS data format, so support may be limited in current mapping software.
On Microsoft Windows, open the .lgo file with MapViewer. If the file does not open, the installed version of MapViewer may not support this legacy USGS format.
Open the file in MapViewer and use the program's export or save-as function to create a format it supports. The available output formats depend on the version of MapViewer.
Alternatively, use a GIS application that specifically supports USGS Digital Line Graph data and export the imported vector features to another GIS format.
