Description | The DMG file extension was created by Apple and is primarily used on Macintosh computers and devices. In most cases the DMG file is used to give the Mac devices the ability to install different types of files and software that originate from the internet. The DMG file is essentially a mountable disc image that shows up on your desktop when it is opened. The file contains raw data that is usually both encrypted and compressed. Mac systems treat DMG in the same way they would treat a disc that was inserted and they instantly try to open or “run” the file. | ZIP is an archive file format that supports lossless data compression. A .ZIP file may contain one or more files or directories that may have been compressed. The .ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. |
Technical details | The DMG file extension was specifically designed for Macintosh computers and users are likely to have a lot of trouble if trying to use them on a Windows device. There may be instances where one can convert the files, but it probably needed to look for additional utilities that will allow the file to be accessed from the chosen device. There are some also executable files that can help with this. However, if the original DMG file was password protected by Apple, those executable applications may not work. The DMG file has several different formats that are used and these include Linux, Fat32, UFS, ProDOS, HFS and HFS+. | ZIP files are archives that store multiple files. .ZIP allows contained files to be compressed using many different methods, as well as simply storing a file without compressing it. Each file is stored separately, allowing different files in the same archive to be compressed using different methods. |

Description | PDF – is a cross-platform extension necessary for the visualization of printed materials in electronic form. It is developed by Adobe Systems using separate PostScript resources. PDF documents can exist separately from the OS or hardware tools with which they were developed. Files of this format do not have restrictions on the length, several types, and image options, as they allow you to embed various multimedia tools, scan-line, and vector images. They are supported by Adobe Reader and many browsers, providing the plugin is installed. |
Technical details | PDF supports color models CMYK, RGB, shades of gray, and also it has its technical formats for performing the exchange of finished documents. Any file contains a description of a 2D or 3D document with all the necessary components (scan-line, vector graphics, text, and more). The extension does not encode data associated with the software or OS used to develop and view it. |

Description | DWG is binary file formats used to store two and three-dimensional images mainly used by devices that use computers in design development. The file format's initial development was in the 1970s and is currently used by professionals like architects, engineers, and designers. Licensing for the AutoCAD application is by Autodesk, who owns the application, and it is commonly used as the standard for most CAD drawings. The auto desk has been resistant to people determining their source code and placing watermarks on the different released versions. |
Technical details | Files in the DWG format possess vector image data and metadata, which mainly using binary coding. A display of the DWG is executed based on instructions that came from data related to an image. Files created by AutoCAD are verified to increase the validation of the files. Software like the Autodesk DWG Trueview allows free usage but lacks the TrueConvert software. The free software allows users to view files while utilizing features like the measure and mark up, organization of sheet set and tracking their progress. For software like DraftSight, DWG files can be created, edited, and viewed. LibreDWG is developing free software libraries for files in the DWG format due to the absence of open-source viewers for this format. |
