I just tested uploading a library from my Android device and synchronizing that to my Windows 10 device (which had no library at all). I didn't encounter a single error of any kind and certainly did not see the kind of invalid paths I saw in the screenshot you provided. So this leads me to believe something is fundamentally wrong with the file paths in your library/database. I'm going to need you to share a library backup file with me (send a link to mike@zubersoft.com), or at the very least send me mobilesheets.db. If you want to copy the database file, you'll need to enable Settings->Storage->Expose Database, and then it will be found in your storage location. Without that, there will be no way for me to figure out why you are seeing those errors.

Thanks,
MIke
