The main purpose of this conversion is the security concerns as a lot of users distrusts. The DMG file has several different formats, including Linux, Fat32, UFS, ProDOS, HFS, and HFS+. In most cases exe to zip conversion is used to change change self-extracting archives (.exe) to simple ZIP archives (.zip).This can be achieved using many of the currently available file managers and/or file compressors, such as WinRAR, WinZIP etc. However, if the original DMG file was password protected by Apple, those executable applications may not work. There are also executable files that can help with this. There may be instances where one can convert the files, but it probably needed to look for additional utilities to allow the file to be accessed from the chosen device. 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. Mac systems treat DMG in the same way they would treat an inserted disc, and they instantly try to open or "run" the file. It’s bigger than before, but you can take it outside the directory and it will. Go to the dist > myscript directory and there will be only one file myscript.exe. When you look at the files generated, there are 3 directories. The file contains raw data that is usually both encrypted and compressed. If you want all generated files in one executable file, type pyinstaller -F myscript.py. The DMG file is essentially a mountable disc image that shows up on your desktop when opened.
In most cases, the DMG file is used to give the Mac devices the ability to install different types of files and software originating from the internet.
The DMG file extension was created by Apple and is primarily used on Macintosh computers and devices.
