Windows Shortcut Rename File
Change file extensions in bulk using rename command. We can change the extension of a set of files in one step using rename command. For example, you have set of files with extension.html and you want to rename them to.txt. Rename command works in all Windows versions – XP, Vista and Windows 7. To rename large groups of files simultaneously, select them all, right-click the first one, and choose Rename. Type in the new name and press Enter, and Windows renames that file. However, it also renames all your other selected files to the new name, adding a number as it goes: cat, cat (2), cat (3), cat (4), and so on.
