what are the file properties
When a file is created on a computer it is automatically given a set of properties such as date, size, and format. Changing properties can allow you to personalize the organization and synchronization of files on your computer. You can manually change some attributes in Windows 7 and Vista by using the Details pane at the bottom of each folder window. You can also access the Properties menu of the chosen file. If you use Mac OS X, file properties are called permissions, which you can change using either the Finder or a downloadable application. This guide shows how to change file attributes on both Windows and Mac OS X platforms.
