This is on a nexus 4 emulated sd card. I do get the full directory structure created when setting up that folder again. I also do see subdirectories created automatically as they are created on the sync master. So it looks like directories are always automatically synced, even when file sync is selective? I'm not exactly sure how I got into that position, but its possible I deleted the directories manually..... I am using btsync for offline map files for Orux Maps. Selective sync means that all the files are readily available when I need them, and I can save space on the phone by not having all the files present all the time. I suspect I got into this situation by deleting a directory containing an unused map to free up some space on the phone. I later want to access that map again. I was expecting btsync to recreate the directory when I start a selective sync for a file inside it. So for now my solution is to free up space by deleting files, but always keep the directory structure intact. Thats doable, but it would be nice if btsync would re-sync the directory structure in this scenario too. Thanks,
