.DOC File Extension

The .DOC files are primarily associated with Microsoft Word, although other word processors, such as OpenOffice Writer or Google Docs, can also open these files. To use .DOC files, Microsoft Word is the primary tool. However, there are other alternatives like WPS Office and OpenOffice Writer.

.JPEG File Extension

The .JPEG (or .JPG) extension is commonly used for images. Many software programs can open and edit .JPEG files including Adobe Photoshop, GIMP, and standard photo viewers included with most operating systems like Windows Picture and Fax Viewer and Preview on macOS.

.EXE File Extension

Last but not least, .EXE files, short for executable. This extension is strictly tied to the Microsoft Windows operating system. It denotes an application that can be executed or run as a program on the computer. It cannot be opened or used in any other manner. Standard security procedures should be followed when executing an .EXE file given their potential for carrying and transmitting malicious software or viruses.
