The release image is not yet available. For installations running 1.57, use the [1.57 documentation](/en/v1.57/overview). Attach files directly to your chat messages — images, spreadsheets, PDFs, Word documents, presentations, and more — so Zylon can read them and use them as context when responding. Ask your IT administrator to enable file attachments in your system configuration [with the Operator Manual](/en/v1.58/operator-manual/configuration/features/overview) if you don't see this option. *** ## What you can do with attachments * Ask questions about a document, spreadsheet, or image you've just attached * Get a summary, explanation, or analysis of its content * Use a file as context for problem-solving or decision-making * Attach more than one file to the same message * Combine attachments with a text prompt for more specific instructions *** ## How to attach a file There are two ways to attach a file to a message: 1. Click the **+** button in the chat box, then choose **Add images & files**, and pick one or more files from your device. 2. Or simply **drag and drop** files straight onto the chat box. The Add images & files option in the chat message box Once attached, each file shows up as a chip above the message box — add your question or instructions and send. A file attached and ready to send with a chat message Your message keeps the attachment alongside it in the conversation, so you can always see what Zylon was looking at. A sent chat message showing the attached file *** ## Supported file types * **Images** — JPG, PNG, GIF, WebP, SVG, BMP * **Documents** — PDF, Word, PowerPoint, Excel, CSV/TSV, plain text, HTML, RTF, ODT, EPUB, Outlook email (`.msg`, `.eml`) Exactly which file types and how many files you can attach depends on how your admin has configured Zylon for your organization. *** ## Limitations * The number of files per message and the maximum file size are set by your admin, and may vary by file type. * If a file is larger than usual, Zylon warns you before continuing — you can still send it, or add it to the project's Knowledge Base instead, which handles large files better. * Understanding an image depends on its clarity and resolution; very large or complex files may produce less detailed results. * Your organization's selected AI model has to support the type of file you're attaching (for example, image understanding).
