❓ SecuRooms: Error when downloading end-to-end encrypted folders

Error description

When you attempt to download a complete folder or data room from an end-to-end encrypted SecuRoom (E2E), your browser will prompt you for a destination folder.

If you select the regular Windows Downloads folder or your Desktop, the download will fail with an error message, and you will be asked for the path again with every attempt.

Solution for users

To successfully complete the download, you must not use system folders within your user profile.

1. Create a new folder outside of your user profile directly on your hard drive (for example C:\Temp or C:\FTAPI_Downloads).
2. Restart the download in the SecuRoom.
3. Select the newly created folder as the destination in the dialog window.

Note: This restriction only applies to downloading entire folders in encrypted data rooms. Individual files can still be saved to your regular download folder without any issues.

Technical background for administrators

The reason for this behavior lies in the way E2E-encrypted data is processed:

• Unencrypted folders: Here, the FTAPI server bundles all files server-side into a .zip file. This file is downloaded using the browser's standard download mechanism.
• Encrypted folders (E2E): Since the server cannot read the data, a browser technology is used that maps and decrypts the folder structure directly on the user's local file system. Because this technology requires extensive write access, the system blocks this for protected system folders (such as the user profile) for security reasons.
