Posting this error message. Having trouble syncing; Zotero desktop app on Mac freezes and gives rainbow pinwheel for about a minute if I try to interact with it while the sync wheel is spinning. Error log follows.

Yes, you cannot sync extremely large files. See this comment for the best way to deal with it (Replace "4DNU3GRL" with "RYLWSK27" and "MS3VVCS8").
