File permissions for increased security

Safeguard the work you share

Manage granular file permissions

hg0088登入It’s important to have control over what people can—and can’t—do with the data you share with them. Dropbox granular file permissions give you the power to control who can access folders and files, and what kind of access permissions they have for each one.

For example, Dropbox lets you set group permissions, so you can share a specific image file with your team—without giving them read or write permission for the more comprehensive or private folder it lives in.

Send view-only files

You can share view-only links—these allow recipients granular permissions to view, comment on, and download—but not edit—the original files. You can also set a passwordhg0088登入 and an expiration date for your links so they’re off-limits once you’ve completed your project.
