Easily Change File Extension From Context Menu

Changing extension of files is quite a chore in Windows. First, you have to enable display of file extension in explorer by choosing the appropriate option in Folder Options dialog box and only then you are able to edit the extension of the file. After you are done, it is wise to disable the option once again because it is very easy to accidently mess with the file extension when renaming a file. A file with an incorrect extension wouldn’t open in its intended program.

When I moved to Windows 7, I sorely missed a program called Properties Plus that I used with Windows XP. Properties Plus allowed me to quickly change extensions of any file from explorer’s context menu without going through multiple dialog boxes. Sadly, Properties Plus doesn’t work on Windows 7, but there is a new program that works not only Windows 7 and Vista but on Windows XP and 2000 as well.


The program simply called Change File Extension Shell Menu, after installation, adds a new ‘change file extensions’ entry to Explorer’s context menu. To change a file’s extension select this item and enter a new extension.

You can also change file extensions in bulk by selecting any of files together. It is also easy to undo any changes made. Just press Ctrl+Z and all changes will be reverted one file at a time. Keep pressing Ctrl+Z until the extensions for all desired files are restored.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.
