Which is why I didn't realize that KOReader had some file management functionality until I started poking around this morning. That said, since the functionality does exist and Xen did bring it up, why not correct myself?

It also depends upon how a person uses their ereader. I noticed that PBChess included a notepad and calculator, so clearly someone thinks that adding a few simple functions to an ereader has some value. Since I use mine as a reader and only a reader, it's not something that I'm interested in -- yet people who are interested in it may want such information.
