I assume that the Jam, like the Sport, organizes folders and files by when they were added as vs. otherwise (apart from when you are using the database). A way to counteract this is to use a program like FAT Sorter periodically, which in essence sorts the files then there anew. This may help you with at least part of your issue.

As to your final comment: the Clip+ still can be found . . . . ;) Check out the SanDisk Outlet store. http://shop.sandisk.com/store?SiteID=sdiskus&Action=DisplayCategoryProductListPage&categoryID=13937600&resultsperPage=100
