File Attachments
Upload and manage supporting files without moving evidence out of its Qarion record.
Overview
Attachments are available across products, data domains, master data, issues, meetings, documents, analyses, repositories, contracts, and data-question messages. The exact upload and delete actions depend on your access to the parent record.
Uploading Files
On Products
Open the product detail page and navigate to the Attachments tab. Click Upload or drag and drop your files into the upload area. The file appears in the attachment list after upload finalization.
On Issues
When viewing an issue, click the Attach button (paperclip icon) in the toolbar. Select one or more files to add them to the issue timeline.
On Meetings
Open the meeting record and scroll to the Attachments section. Click Add Attachment and select the files you want to upload.
The same pattern applies to other supported records: open the relevant attachment, asset, or discussion area and choose the upload action.
Upload Progress And Recovery
Qarion uploads supported attachments in resumable parts. The interface reports progress while those parts are committed. If a transient network or server error interrupts a part, the client reconciles stored progress and retries it.
If you return to an interrupted upload in the same browser, select the original file again. Qarion resumes only when its name, size, and last-modified value match the saved session. Selecting a different file starts a separate upload; Qarion never substitutes it into an existing session.
An attachment is not visible on the parent record until every part is stored and the upload is finalized. If a session has expired or been cancelled, start a new upload.
Supported File Types
The attachment service accepts common documents (PDF, Word, Excel, and PowerPoint), images (PNG, JPEG, and WebP), text and source files, notebooks, CSV, JSON, XML, YAML, and generic binary files. The browser can reject a file whose reported content type is not on the approved list.
Maximum attachment size: 10 MB per file.
Managing Attachments
Downloading
Click the file name or the Download icon to save a copy. Qarion can resume or seek within downloads when the browser sends a byte-range request and the configured storage backend supports it.
Deleting
Click the Delete (trash) icon to remove an attachment. Deletion is available only when you have delete access for that attachment and its parent.
Best Practices
- Use descriptive names — Rename files before uploading.
- Keep sizes reasonable — Compress files when appropriate and keep each attachment at or below 10 MB.
- Organize by purpose — Use consistent names for evidence and revisions.
- Resume with the original file — Re-select the same local file after an interrupted upload.
- Remove stale evidence deliberately — Confirm that comments, reviews, or published records no longer rely on a file before deleting it.
Troubleshooting
| Problem | What to do |
|---|---|
| The file type is rejected. | Export it to a supported format or ask an administrator which content types are approved. Renaming the extension does not change its reported content type. |
| The file is too large. | Reduce or split the file so each attachment is no larger than 10 MB. |
| An interrupted upload does not resume. | Select the exact original file. If the session expired or was cancelled, start a new upload. |
| Upload reaches 100% but no attachment appears. | Wait for finalization, then retry. If it continues, ask an administrator to check the storage backend and transfer service. |
| A download restarts instead of resuming. | The storage backend or proxy may not support byte ranges; download the file again from the attachment action. |
