can my sansa connect work as a flash drive for like a powerpoint
U can save your powerpoint file onto the flash drive. But that’s just about it unless your interested in U3. Some programs can help you with this.
If you rename your PowerPoint file so that it has an .mp3 extension, you can copy it to and from the Connect’s internal memory. But I can’t guarantee the Connect won’t hang if you restart it and it attempts to process the file (ie, look for MP3 tags etc.). You’ll have to try it for yourself.
