creating slide shows on flashdrives

Hi.  My external hard drive crashed. I had a backup.  I took the opportunity to restructure the directory for the folders in my catalogue and then created new albums in a new structure.  The album structure carries reference numbers for indexing purposes.  Thus:           H Holidays           H.1 Local    H.1.1  seaside    H.1.1.1  The Cape

H.1.1.2 East coast     H.2 Overseas     etc

I wish to create slide shows using this indexing system on flash drives.

How do I achieve this?

best wishes

Darrell
