Lets say you have a digital camera and create lots of pictures when your on holidays. Those cameras normally name the pictures DSC000001.jpg and its kinda hard to search through those pictures. It would be much easier if you could rename those files with ease so that the filename itself gives you information about the pictures. Pictures of your December 2005 trip to Colorado could be named 2005_12_colorado_001.jpg for example. Easier to recognize isn´t it ? Well, Bulk Renamer can do this for you.
