Upload problems
- Confirm Turnstile shows success.
- Check that the transfer is within your current quota.
- Keep the browser tab open during active upload.
- If an interrupted upload is still valid, use the resumable flow where available.
Quick help for common PsiDrive issues.
PsiDrive is designed to be simple, but encryption, browser permissions and temporary transfers can create a few predictable failure modes.
Download problems
- Use a current version of Chrome or Edge for direct-to-disk streaming.
- Make sure the full share link, including the portion after
#, is present. - If the transfer is password protected, enter the exact password supplied by the sender.
- A 404 can mean the transfer expired, was deleted, or was already consumed.
Frequently asked questions
Can PsiDrive recover my encryption key?
No. The design intentionally keeps the AES key out of server-side storage. If the key portion of the share link is lost, PsiDrive cannot reconstruct it from the encrypted file.
Why did my transfer disappear?
Guest transfers are temporary. The normal retention target is 24 hours, and delete-after-first-download removes the transfer after one successful completed download.
Which browsers are best?
Current Chrome and Edge provide the direct-to-disk browser API used for the most memory-efficient large-file download path. Other browser fallbacks can be added separately.
Where is PsiDrive hosted?
The current V1 stack runs on Cloudflare infrastructure: Pages for the frontend, Workers for the API and scheduled cleanup, D1 for metadata, R2 for encrypted objects, and Turnstile for anti-abuse verification.
