Critical Data Loss After Using “Delete Old Version” – Cursor Deleted My Entire System

[SS1900]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Hello everyone,

I encountered a catastrophic issue while working on a project with Cursor, and I need to bring serious attention to it.

While working on a program, I chose the option to delete the old version of my project. To my shock, this didn’t just remove the old files — it completely wiped out my entire computer. Everything on my C drive, all my installed programs, backups, and months of work — even Cursor itself — were deleted instantly.

I’m extremely careful with my system, and nothing else was running that could have caused this. This was entirely triggered by Cursor’s action. The damage is enormous, both personally and professionally, as I’ve lost irreplaceable work.

If this is a bug or system-level malfunction, it poses a massive risk to anyone using the software. I urge the developers to investigate this immediately. I can provide logs and details about the environment if needed.

Depending on the outcome and response from the team, I may consider taking legal action due to the scale of data loss caused by this incident.

Has anyone else experienced something similar, or does anyone from the Cursor team have insight into what could have caused such destructive behavior?

Thank you,

Steps to Reproduce

Open a project in Cursor.

Save multiple versions of the same project locally (for example, version 1, version 2, etc.).

Use the “Delete old version” option or similar cleanup action provided by Cursor.

Confirm the deletion when prompted.

Observe that the program begins deleting far beyond the project folder — including:

All files in the C: drive

Installed programs

Personal backups and work files

Even Cursor itself

Expected Behavior

Only the old version of the specific project should be deleted — no other files or system data should be affected.

Actual Behavior

Cursor triggered a full deletion process that wiped out the entire system drive, removing all programs, backups, and user data, effectively rendering the system empty.

Additional Information

OS: [insert your OS version here, e.g. Windows 11 Pro 22H2]

Cursor version: [insert version number if known]

No third-party cleanup or antivirus software was running at the time.

The deletion occurred immediately after confirming the “delete old version” action.

Hey, I’m very sorry to hear about the data loss, that sounds extremely distressing.

To figure out what happened, please share:

• A screenshot or the exact location of the “delete old version” option you used (which menu or button?)
• Cursor logs from the time of the incident (Ctrl + Shift + P → Developer: Open Logs Folder)
• Windows Event Viewer logs around the time of deletion (eventvwr.msc → Windows Logs → System)
• What you mean by “multiple versions” were these separate folders, or were you using Git or another tool?

Immediate recovery steps:

• Check the Windows Recycle Bin
• Try Windows File Recovery: winfr C: C:\Recovery
• Check for restore points: rstrui.exe

I’ll pass this to the team, but we need these technical details to understand what happened.
