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.
