File checks and protection

Uploading, antivirus scanning, and preparing a preview are separate stages. A file can be fully transferred without being ready to download. Check the version’s status, not just the transfer percentage.

Wait until the file is ready

1. Follow progress in File transfer during upload.
2. When transfer finishes, wait for Awaiting scan or Virus scan to complete.
3. Use the file after its status becomes Done. In the version list, a successful scan is shown as Scanned.

For a public file request, the sender sees Received for scanning. The recipient checks the final state inside ClodDoc.

When you upload a new version, the previous ready version remains available while the new one is processed. An external link continues to point to the version preserved when that link was created.

Understand check failures

Status	What to do
Awaiting scan / Scanning	Wait for the check to finish. Contact your company administrator if the wait is unusually long.
Quarantine	The file was isolated following the check. Do not try to bypass the restriction by renaming or repeatedly uploading it.
Scan failed	The check did not complete successfully. An administrator needs to investigate; the status alone does not establish that the file is infected.
Upload failed	The transfer failed. Check your connection and whether you can resume the upload.

When asking for help, include the file name, visible status, and time of the error. If the application provides a request code, include it. Do not post passwords, email codes, or complete protected URLs in shared channels.

Why a preview or search result is missing

Supporting a format for upload does not mean its contents can be previewed or searched. Text previews and indexing currently support UTF-8 TXT, MD, and CSV files, within the limits on processed text.

Do not expect text previews or content search for PDFs, images, office documents, videos, or archives. This feature does not perform optical character recognition on images. You can search for those files by name independently of text indexing.

Preview not supported and Indexing not supported do not mean a file is damaged or unsafe. A checked file can be available to download without either feature. See versions and previews and search.

What an administrator can do

An organization administrator can open File processing → Processing queue. For an unsuccessful check, Retry check requires an explanation for the administrative action.

Quarantined files have a separate Allow file after quarantine action. This is a deliberate administrative override recorded in the audit log, not a new clean antivirus result. It should not be treated as the routine way to fix any upload problem.

Emergency access is a separate administrator action requiring a reason and confirmation with the current password. It gives temporary read access for 30 minutes and is audited. It does not transfer ownership or grant editing rights.

Match access to the task

Give colleagues View instead of Edit when they do not need to change material. For external sharing, set an expiration date and, where useful, a download limit. Send the password separately from the sharing link.

ClodDoc encrypts stored files; the server performs security checks and supported processing. This is not end-to-end encryption that prevents the server from reading contents. Antivirus scanning also does not replace your company’s document-handling rules.
