How to use flexible file names on Dropbox

Flexible file names allows users on the Dropbox desktop app for Windows to successfully sync files and folders with names that contain special characters. Previously, these files and folders would be visible on dropbox.com but wouldn’t appear in the File Explorer despite the Dropbox desktop app being fully synced.
 

Now special characters are replaced by “_“ (Unicode character U+005F) when syncing to Windows devices. This change happens to file and folder names if the name ends with a period or contains the following characters:

• <
• >
• :
• ”
• |
• \
• ?
• *

For example, if you have a file named “test:april.txt”, that file will sync to File Explorer as “test_april.txt”. Additionally, if you have a folder named “Important stuff.” it’ll be converted to “Important stuff_”.

How to turn flexible file names on or off

You‘ll see a notification when you’re syncing files that contain special characters. Click Opt-out or Opt-in on this prompt to go directly to Preferences.

5. Toggle Flexible file names to On or Off.
