When enabled, a Couchdrop support team member can generate an access token for your account. Disable this setting if you do not want Couchdrop support to be able to access your account. ## Advanced Protocol Options ### Async FTP uploads Allows Couchdrop to continue uploading or syncing a large file after the FTP client has closed its connection. This can help prevent client-side timeouts when transferring large files over FTP. ### Async SFTP uploads Allows Couchdrop to continue uploading or syncing a large file after the SFTP client has closed its connection. This can help prevent client-side timeouts when transferring large files over SFTP. ## Limits ### Upload file size limit Sets the maximum file size Couchdrop will accept for an upload. Couchdrop applies a default upload file size limit. Contact if you need this limit increased. ### File list limit Sets the maximum number of files and folders Couchdrop returns when listing a directory over SFTP, FTP, or another supported protocol. For folders containing a large number of items, the configured limit may mean that not every file or folder is returned in the directory listing. Contact if you need this limit increased.
