What types of files can I store or view on Dropbox?
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.
Files that preview as a document
Dropbox previews .pdf documents in their native format. In addition, the following formats are converted to .pdf for previews:
- .doc and .docx
- .ppt and .pptx
- .pps and .ppsx
File size limits for previews are:
- .doc and .docx: 160 MB
- .xls: 40 MB
- .ppt and .pptx: 288 MB
Note: Previews 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.
Files that preview as an image
- .jpg and .jpeg
- .tiff and .tif
- .eps (web only)
- Previews for image files can't be shown if they're greater than 50 MB or 50 mega pixels
- When saving .psd files you can set a preference to maximize compatibility, which we recommend
Files that preview as a video
- DRM-protected files cannot be previewed
- There is no file size limit for video file previews
- When you save a video in your Dropbox you will be able to watch the full video from a Dropbox preview page
- Dropbox Business users who receive a shared link to a video can view the full length on a preview page
- Dropbox Basic and Pro users who receive a shared link to a video can view the first fifteen minutes on a preview page (these users will need to download the file to their computer to view the full length)
We add to this list frequently. Feel free to check back here occasionally for your favorite file formats.
For our advanced users
File names incompatible with other operating systems
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, use our bad file check tool.
A warning regarding metadata and FAT32 drives
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.
Using referenced files in Dropbox
We strongly recommend against methods that add referenced files (symlinks, junction points, or networked folders) to the Dropbox folder. Using reference files can cause high CPU usage, poor syncing performance, permissions issues, and quota usage disparities.
Turning on xattr support in Linux
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.
