I like that File Viewer Plus displays metadata for every file format I open, so I can see what information is stored in the file, including author information for documents and EXIF data for images. It's a nice program to have whenever I encounter unknown email attachments or files in my Downloads folder. The file browser is also nice since I can quickly locate and preview files.
