A DWG file (also known as a Drawing file) is one of the older Computer Aided Design (CAD) formats and is primarily associated with Autodesk's AutoCAD application. The format started out as a format for storing 2D CAD drawings but has evolved to store other CAD-related data, including full 3D CAD models.
The format stores the core CAD data, such as points, lines, elevations, and other 2D and, in more recent versions, 3D modelling data, along with other important metadata related to the drawing. The DWG format is proprietary and is intended for use with the AutoCAD application only.
Although designed for the AutoCAD application, there are other 3D CAD and modelling applications that can open DWG files. As the format is proprietary and has been updated many times over the years, opening a DWG file with any application other than AutoCAD will be met with varying degrees of success.

The PCX file format is the native format of the 1980s graphics application PC Paintbrush. Created by ZSoft, PC Paintbrush ran on the MS-DOS operating system and allowed the creation of raster bitmap images.
The file format allowed the storage of image data utilizing simple run-length encoding compression, which resulted in small file sizes. The format has been taken over by more modern formats such as PNG and JPEG, whose superior compression techniques make for more efficient file sizes.
As the PCX format is now classified as a legacy format, support for opening and editing PCX files within modern image editing applications is limited. We do, however, have a series of PCX conversion tools that will allow you to convert a PCX file to most modern formats.
