It
Sorry guys who developed this app but it is useless! It needs a lot more work.
I have about10gb of files on my server and this app cant even keep track of last edited files. It usually replaces document with sync error or keeps saying "new version" available but never opens the document or music file.
I think that if you releasing something in to production you should do extending testing before it goes public. I think your main process of how you sync files are broken. Keep working and you may want to check out how Google drive handles that and get some ideas. Also, desktop client has problems as well.
