Chat links not working anymore

[Serp]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Previously, dragging and dropping a file into the chat or copying and pasting it would create a link, allowing the model to study or even modify the file (if local). But this morning, when I drop a file, nothing happens. When I copy and paste, only the file name (without path) appears as regular text. It doesn’t matter if I try this in new chat session or existing one.

However, linking url works like before.

Steps to Reproduce

1. select file in file explorer
2. drag and drop it to chat

Expected Behavior

Link to the file should appear

Operating System

Windows 10/11

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report.

We need a few details to reliably reproduce:

• Are you dragging from the Explorer side panel inside Cursor or from Windows File Explorer?
• Does adding via @ → Files & Folders work for the same file?
• Does it reproduce after restarting Cursor, in a new window, and in an empty project?
• Could you attach a short screencast and errors from DevTools: Help → Toggle Developer Tools → Console, then reproduce the drag-and-drop/copy-paste and share the logs?

A couple of temporary workarounds:

• Try @ → Files & Folders and select the file
• If you’re dragging from Windows Explorer, try dragging from the Explorer panel inside Cursor instead

It looks like a recent regression. Once we get details and logs, I’ll escalate it as a bug report. Please share your results and screenshots.

1. Windows File Explorer, outside workspace
2. it cannot reference outside workspace(?)
3. yes
4. Video:
5. Console stays blank
6. I did notice, that dragging .pdf and .csv files instead .json still works. Also .json was working in previous Cursor version from yesterday. Even renaming .json to .jsn works. So it is isolated to .json file extensions.
