Like check which smart folders are there and which databases they use and then load only those database files. And on demand you load other files on request into memory. Or maybe load them only when a folder is accessed that uses them. Maybe you could built in some anonymized analytics to see which database files are always loaded and after a month (with later tweaks) you should know which would be relevant because 80% of the users use them all the time, so you load these by default and others only on demand. Or isn’t that possible because you need to load them completely into memory to write to them? Couldn’t you then load them only every “time interval” write the changes and then unload them? Just some ideas - not a real programmer myself. Niels
