Anything you save to your computer can be saved to your Dropbox, including all of your documents, movies, music, photos, internet downloads...you name it.
Dropbox has the ability to open and preview files straight from your browser. The following file types are currently supported.
Dropbox previews .pdf documents in their native format. In addition, the following formats are converted to .pdf for previews:
Note: Previews for the formats listed above can't be shown for files greater than 20 MB. Previews also can't be shown if the file is corrupt or the .pdf conversion process takes too long.
The following text and code formats are supported:
Note: Previews for text and code files can't be shown if they're greater than 4 MB.
Note: Any files that are password-protected can't be previewed.
We add to this list frequently. Feel free to check back here occasionally for your favorite file formats.
Dropbox won't sync files that are incompatible with other operating systems. In many cases, all that is needed to make the file compatible is simply changing the name. To find out what files aren't syncing to your other computers, check Bad Files Check or read more on file incompatibility.
Some documents have file attributes, or xattrs, in data attached to the file. We call this data metadata. Operating systems use metadata for many different ways: storing the icon, labeling your documents, attaching information to the file, permissions, etc... Dropbox supports xattrs on all platforms. However, thumb drives and portable drives that use the FAT32 file system do not support metadata. If your Dropbox folder is on a FAT32 drive, unfortunately it is impossible to retain metadata when the file is moved or renamed.
Some Linux distributions have xattrs turned off by default. If you are running a Linux distribution with an ext3 or ext4 file system, it is possible to turn on xattr support, typically through your
/etc/fstab settings file. Please refer to your Linux distribution's documentation for instructions.
