Properties may refer to any of the following:
1. In general, properties are the settings of an object on a computer. For example, you could right-click highlighted text and view the properties of that text. The properties of a font or text could be the font size, font type, and color of the text.
As seen in the picture, this right-click menu gives you all of the properties and options of the highlighted text. From this menu, we can change the font size, type, color, and other properties.
2. When dealing with files, file properties are pieces of information about that file, which can typically be accessed via a menu item (often called "Properties"). For example, in Microsoft Windows you can access the properties of a file by right-clicking the file name and selecting the menu item Properties. Viewing the properties of a file gives a window similar to the example below, which displays information about the selected file.
Tip: In Windows press Alt+Enter when any file, shortcut, or other object is highlighted to open the Properties window for that object.
3. With programming, properties are special values that are included within a class/object, usually (depending on the language being used) set using get or set method calls. These are often thought of as a special case that is "in between" a regular data member and a method.
