RecentX lets you tag any file or folder in Windows.

Tags help you access a group of files/folders in just few seconds. However deep they are on your system. This can save a lot of time.

Tags let you label files, folders, apps & websites based on category, file types, projects, etc. They come very handy if you find yourself opening the same set of items each day for a particular project.

Assigning tags to clipboard history items, lets you save frequently used text and images that can be used when sending emails with standard replies.
