To open a cloud file on a borrowed or work computer, first check the device policy and trust it enough to sign in. Use Seedr's supported browser viewers where available, then sign out. A preview avoids an installer; it does not make an untrusted computer safe.

Open a supported file

  1. Check whether the computer policy allows the account and file.

  2. Use a separate guest session on a trusted computer.

  3. Sign in and open a supported video, audio, image, PDF or text file in the viewer.

  4. If preview fails, use an approved compatible tool rather than changing the file extension.

Finish cleanly

Sign out when done, close the guest session and check for any files you deliberately downloaded. Guest browsing is not protection from a compromised device. Use your own device for private financial, identity or work-confidential documents.

Use a device you trust

  • Follow the device owner or workplace policy before signing in or uploading files.

  • On a borrowed trusted computer, use a separate guest session and avoid saving passwords.

  • Sign out and close the guest window when done. Downloaded files can remain on disk; do not handle sensitive documents on an untrusted machine.

Frequently asked questions

Does Guest mode make an untrusted computer safe?

No. It helps separate browser activity, but does not prevent monitoring or malware on the device.

Can a browser open every possible file?

No. Support varies by file type, encryption and device. Use an approved compatible tool if preview is unavailable.
