Attachment file types and virus scanning
Control attachment extensions, upload scanning and approval of reusable video media for your website.
What it is
Attachments defines which file extensions your website accepts and where they can be used. Separate controls govern antivirus scanning. Reusable video approval is a further workflow and does not mean every document or image needs approval.
Who uses it and why
Administrators ask Powerfront to change allowed file types. Supervisors use the policy to understand why an operator or visitor cannot upload a particular file. Eligible video reviewers approve or reject reusable videos and manage their availability.
Where to find it
Powerfront manages Settings › General Settings › Attachments and the scanning controls under Settings › General Settings › Admin › Security. Ask Powerfront to change permitted file types or scanning settings for you.
Reusable-media review opens the Video Approvals window. It is available when the website's video capability is enabled and your account has the required Video Feed permissions.
How it works
INSIDE checks an upload's filename against the website's permitted file types. Each entry has separate Chat, Email and Operator Upload Only choices. Chat covers live chat and supported social or text channels. Potential Unsafe File Type marks types that need a warning before an operator downloads them.
Where a scanner is configured, the upload service scans file content and any supplied thumbnail unless the filename matches an exclusion. With Antivirus set to None, that service does not scan uploads. An unsafe-file warning and an antivirus scan are separate checks.
In Video Approvals, Awaiting Approval and Rejected tabs separate videos needing attention from other media. Status labels include Draft, Processing, In Review, Public, Rejected, Archived, Offline and Private.
Select Approve or Reject while reviewing a video. Rejection requires Reason for Rejecting, which is shown as a comment on the rejected item. Depending on the video and current tab, further actions include Make Public, Make Private, Take Offline and Re-request Approval. Video History shows recorded status changes.
Configure it
- Ask Powerfront to add or edit a file type in Attachments.
- Provide Description and File Extension, and specify File Type.
- Ask Powerfront to set the channel and operator restrictions and, if appropriate, Potential Unsafe File Type.
- Powerfront selects Save.
- Ask Powerfront to review Antivirus and Antivirus Scan File Exclusions separately.
Powerfront support can change image resizing and thumbnail-processing settings for you. These are separate from the extension catalogue and channel permissions.
For reviewers, grant the Video Feed role and Manage Company Video Feed permission. Auto Approve Private Videos allows eligible private videos to bypass manual review once processing is ready and they are submitted for approval.
Powerfront can search the attachment list, filter by channel or operator-only status, and delete individual or selected entries after confirmation.

Limits and good to know
- The file extension must include its leading dot and pass the editor's format check. The editor allows at most 12 characters.
- An extension already in the catalogue cannot be added again.
- Enabling an extension does not remove a channel provider's own attachment restrictions.
- Image resizing dimensions are separate from file-size limits.
- Scan exclusions bypass scanning. They do not grant additional channel permissions.
- Video deletion is blocked when the video belongs to a show. Remove that show association before trying again.

FAQ and troubleshooting
Why can an operator upload a file that a visitor cannot?
Ask Powerfront to check Operator Upload Only for that extension, along with its Chat or Email setting.
Are all uploads scanned automatically?
No. Scanning depends on Antivirus being configured and on the filename not matching a scan exclusion.
Does an unsafe-file warning mean a virus was detected?
No. Potential Unsafe File Type is a warning flag for the extension. Antivirus scanning is a separate process.
Does every file wait for media approval?
No. Approval states are used by specialised media workflows such as reusable videos. They are not a general approval queue for every attachment.
Why can I not approve a video?
Check that video features are enabled for the website and that your account has Video Feed and Manage Company Video Feed access. The available actions also depend on the video's current status and tab.
