What can become a cubby? What can sync?

You can make any standard folder on your computer or other writable media into a cubby. This includes fixed or removable disk such as an external hard disk drive, USB stick (pen drive), Flash reader or similar, including NAS (Network-attached storage). For more information about syncing NAS devices, see Using NAS Devices with Cubby

Are sub-folders included in a cubby?

Sub-folders are also included in your cubby. So for a folder called 2013 with a sub-folder for each month, each month will also be in the cubby and stay in sync.

Which folders can't be cubbies?

If you try to make a non-standard folder into a cubby, you'll see this error: "The folder you chose cannot be made into a cubby."

The folder must not meet any of the following conditions: 

  • Be a subfolder of an existing cubby
  • Be the parent of an existing cubby
  • Be on a read-only media - for example, a CD- or DVD-ROM
  • Have a name that begins with a dot/period, like this: .folder_name_with_period
  • Have a name longer than 255 characters or ending in a space
  • Be a hidden, Windows or System folder or have one as a parent or among its children
    • Windows folder: c:\Windows
    • System folder: c:\Windows\System32\
  • Be a Library or Applications folder or have one as a parent or among its children
    • /Library/
    • /System/Library/
    • /Applications/
    • ~/Library/

Which files can't be synced?

You can keep anything in a cubby. A cubby is just a folder. Anything you can normally store in a folder can be stored in a cubby. You can handle your files like you normally would. Move them, delete them, change them. But keep in mind your changes will be synced to other locations (assuming you are syncing).

That said, the following file and folder types will not be synced:

  • Hidden or system (Windows)
  • Invisible (Mac)
  • Starting or ending with a dot/period, like this: .file_name_with_period
  • With a name longer than 255 characters, ending in a space, containing an ASCII code below 32, or containing any of the following characters: : ? / \ " < > | *
  • Named or starting with any of these prefixes before a dot: com0, com1, com2, com3, com4, com5, com6, com7, com8, com9, lpt0, lpt1, lpt2, lpt3, lpt4, lpt5, lpt6, lpt7, lpt8, lpt9, con, prn, aux, clock$, nul

Note: Synced files are saved without any changes to file extension or format. A doc stays a doc. An xls stays an xls.
