The File Upload feature in Zoho Desk lets agents and customers attach files directly to support tickets and communication threads, keeping all relevant documentation consolidated in one place.
What is it
File Upload in Zoho Desk enables agents and customers to attach files—such as screenshots, logs, or documents—to tickets and messages across any communication channel. Administrators can govern exactly which file formats are permitted or blocked, helping teams enforce security policies without manual intervention [4]. Additionally, through the Zoho WorkDrive integration, WorkDrive files can be added as attachments directly inside Desk requests, with the option to download or remove them as needed [3].
When to use it
- A customer submits a bug report and needs to attach a screen recording or log file so the support agent can reproduce the issue faster [4].
- An agent wants to share a product manual or configuration guide with a customer by attaching it to a ticket reply [4].
- An administrator needs to block potentially dangerous file formats—such as executable files (
.exe) or compressed archives (.zip)—from being exchanged through any support channel to reduce malware risk [4]. - A support team stores reference documents in Zoho WorkDrive and wants to attach them to Desk tickets without downloading and re-uploading the files [3].
- A team lead wants to enforce consistent attachment policies across both inbound customer messages and outbound agent responses from a single admin control [4].
How to access it
Attachment controls are available to administrators on the Enterprise edition of Zoho Desk [4]. To configure permitted file types, navigate to Setup → Security → Attachment Controls in the Zoho Desk admin panel, where you can define allowed or blocked formats for both agent and customer communications across all channels [4]. To attach WorkDrive files to a ticket, agents can use the WorkDrive Gadget available within the Desk request view, which is enabled through the WorkDrive–Desk integration and requires no additional configuration once the integration is active [3].
