Hello. I'm not sure if I'm allowed to post this to current conversation, but I've discovered some traffic peak in my logs, so I guess you're interested in useful shell extensions. Here is a couple didn't mentioned before. Infotag Magic  Windows shell extension that displays extra data stored in the tag fields of  MP3, WMA and Ogg Vorbis files in a tooltip window next to the mouse pointer.  Also it provides a quick preview for plain text files, shortcuts properties and  version information of executable files. Instant ThumbView A tiny image viewer shell extension that displays image thumbnails in a tooltip window, when mouse pointer is hovered over an image file in Windows Explorer. Here is a screenshot:   Context ThumbView A small picture viewer that provides image files preview directly in the right-click menu.  Note. This one is similar to PicaView, but has less functions and is much more lighter. Here is a screenshot:   Hope they will be of help to you. Have a nice day, Leonid
