E.g. you may just copy full structure from FR to VP w/o files - e.g. copy entire music base from FR to VP. When you will have prepared structure, save state using <save command and try to experimenting with <load command


I may tell about state file format.
First 8 bytes keep file's attributes (0x10 is directory attribute), next char is tab character, next 16 digits divided by space contain modify date and time (you don't need it for folders so you may leave zeroes here or paste any wanted value - e.g. taken from another state file), next char is tab, next string keeps virtual path, again tab and real path. If real path is absent, folder or file has no reference to actual object.00000010<TAB>00000000 00000000<TAB>\Music\0001-U2-1987-The Joshua Tree\1987 - The Joshua Tree (MFSL)<TAB>D:\Music\0001-U2-1987-The Joshua Tree\1987 - The Joshua Tree (MFSL)\
But keep in mind that you can't add references to files into physical folder's reference. If you need it, you should make that folder virtual and add references to folders and files into (you may refresh virtual folder's contents using auto-update script so files will be added automatically).
