Upload and resume private original files
Keep a private original-file record for an agreed deliverable and recover interrupted transfers without replacing existing objects.

Before you start
- Your own approved partner account and a confirmed agreement with reserved funding.
- An original video, image, audio or PDF file you are allowed to store; keep a separate original copy.
- A training environment with real Storage configured before practising uploads.
Follow the steps
Open the original-file inbox
Open your agreement, select Deliverables and review, then Private original files. Verify the agreement title and select the intended deliverable group.
What you should see: The inbox contains only your own original-file records. Advertisers and operations reviewers cannot inspect unsent originals through their accounts.
Choose and upload a file
Select Create a new reservation and choose a supported video, image, audio or PDF. The limit is 2,147,483,645 bytes (just under 2 GiB) per file and 100 reservations per agreement, including rejected or expired records. Use a filename without folders, then choose Upload original.
What you should see: A unique record is created and upload progress appears. The original is stored privately; no existing object is overwritten.
Pause or recover a transfer
Use Pause upload and Resume upload when needed. After returning to the page, select the existing upload reservation and the exact same original file before choosing Upload original again. Reservations last 24 hours; after expiry, preserve the old record and create a new reservation if quota permits.
What you should see: An available resumable session continues its transfer. Another account, a different file or an expired reservation cannot reuse the upload authority.
Check a completed upload
After transfer completion, inspect the inbox status. If the transfer finished but the result is uncertain, choose Check completed upload on the existing record rather than creating a duplicate.
What you should see: Matching stored metadata moves the file to Waiting for file verification. In an environment with the qualified worker enabled, independent file checks then produce File verified · still private or File rejected. A verified file displays its SHA-256. Pending or in-progress status is not a successful check.
Preserve the handover
Record the agreement, group, file reference and observed state. Keep the original. Download verified original creates a private link that expires after 60 seconds; downloaded copies remain on the receiving device. For a verified video, Create private clips opens the trim and centered-crop workflow. To share a verified file, open the matching delivery, select it under Verified original files, classify its evidence type and explicitly submit the delivery version.
What you should see: Upload and verification alone keep originals private. Only selected files become available to the advertiser and authorized support after submission; verification does not establish rights, acceptance or payment.
If something goes wrong
Upload is denied or interrupted
Check account approval, agreement/funding state, reservation expiry and network access. Reopen the existing record before retrying; do not create another account to bypass controls.
The stored file is rejected
Size, type, file structure, scan limits or file checks may have failed; repeated verification-service failures can also exhaust the retry limit. Preserve the reference and ask operations to review the recorded reason. Do not resubmit an unsafe file or replace an existing object.
File verification stays pending
Give operations the file reference and actual environment. Do not label it verified or substitute a screenshot of upload progress for independent file checks.
Try it in training
Complete OPS-15 in training: create one reservation, interrupt and resume the same file, recover an uncertain completion, confirm cross-account privacy and observe a mismatched-file rejection. Record actual Storage evidence, observe the qualified worker result and then use OPS-14 for explicit attachment and review. Unobserved checks remain open.
Check your understanding
Does Waiting for file verification mean the work is ready for advertiser acceptance?
No. Upload metadata was recorded, but independent byte checks and an explicit delivery submission remain separate. The private inbox neither shares the original nor creates payable earnings.
