i have been using Sync for a long time to synchronize parts of my 6tb music collection to a 400gb sd card on my Samsung Galaxy s9. I've been doing it folder by folder of artists (for example i have a folder called "Byrds, The" that has all their albums in it and i have been doing that with any other artist i want to have on my phone too. i used to have a 200gb card and had no issues, now that i have the larger card i obviously have more folders syncing. the problem is - now that i have these extra folders Sync can't seem to handle it - it takes FOREVER to even load and then once it does i get almost no speed whatsoever and even sometimes LOSE my internet connection totally (whether its wifi or mobile data). is there a limit to how many folders you can sync with this program? the other problem is when i try to do anything at all - changing status of folders, deleting them, etc - i end up with a white screen that makes me have to restart Sync and start trying to change things all over again. this is incredibly frustrating.
