It is so simple creating and using Playlist function, I don't know why you think is so complicated, Lee...
John, the playlist file of Genos is a csv file, a TAB delimited file, which can be opened with a text editor. If you open a tsv file you will check that first row is a fixed "column name" row, which has to be present on every file, even if you will create that file from Excel or Notepad. Next rows are data rows (records) in that playlist file.
The structure is so simple and so intuitive, I don't know why for some people is "complicated"
A record in a playlist has a Title, a path to the registration bank, the number of the registration from selected registration bank to load automatically, and the viewer which will be displayed automatically when you select and Load the playlist record.
The path to registration bank files contains a letter (I: , J: , etc). This means the registration bank files has to be present on that location. You cannot change anything on that path (move content in a sub-folder) because it will not work anymore. So, if you have I:/Folder1/Folder2/Myreg.rgt on a record, it means the registration bank has to be on the first USB (depends on how many USB sticks you have inserted in your keyboard), in a folder named Folder2, which it is in a folder named Folder1, which is present in the root of your USB stick. You said you have created a root folder. You cannot create a root folder on a stick, if you double click the USB letter on the PC, the open window will showing the root folder. Root means the first level of hierarchy on a device, which will be I:, or D:, or E: or whatever... If you have created a folder which you named it "Root" (or whatever) and you have put all the content in that folder, you practically changed the path for the elements/records in the media (USB stick, HDD, etc), which means the keyboard will not find anymore the file which is wrote in the playlist file.
ie: The new path for your registration bank files is I:/Root/Folder1/Folder2/Myreg.rgt which is not the same with path wrote in playlist file, I:/Folder1/Folder2/Myreg.rgt . Genos will try to find Folder1 in the USB, which is not present because you moved it in a folder named Root.
It is very simple.
Lee, I have made a software which automatically will sort your playlist file, you can edit records, delete records, you can add records to your playlist, or append another playlist (concatenate 2 or more playlist files).
