Many documents, such as photos, music, movies, and paper documents, etc., have been transformed to digital files for archiving purpose. Digital files are easier to keep and duplicate and last much longer without degradation. However, managing these ever increasing digital files presents a major challenge to most users. A major problem in managing files is how to add annotations to files. Common annotations include authors, dates, versions, summaries, reader’s opinions, keywords, etc. Different kinds of documents may carry different annotations. For example, annotations for a digital photo may also include the place where a photo is taken, the photographer, the equipments used to take the photos, etc. The annotations help to organize the files and to locate desired files in a sea of files. For instance, a user may want to locate all photos taken with a specific camera. Traditional file managers allow very limited and inflexible ability for annotations. A user sometimes uses file names as annotation, such as “SW DVD5 Office Enterprise 2007 W32 ChnTrad #1 PA BP MLF.X12-19568.img”. This results very long file names. Still, long files are incapable of carrying all the desirable annotations. Based on these observations, we designed and implemented a new file manager that is centered around annotations. The new file manager provides all the necessary operations on the annotations.
