Forum reply: a second Antigravity user says a clean-up delete command meant for a D: folder resolved to the C: root and wiped their whole Windows user profile
In a reply posted on 8 October 2026 to a Google AI developer forum thread about an Antigravity data-loss incident, a second user says that their entire Windows 11 user profile (Desktop, Downloads, AppData and browser data) was wiped out during a routine clean-up session with the agent. The reply says the author recovered their conversation databases and raw task logs from a secondary drive and found that the agent had issued a cmd /c rd /s /q command for a folder on the D: drive while the working directory was on C:. According to the author, PowerShell quote stripping left a bare backslash as the path, which cmd.exe resolved to the root of C:, so the command recursively deleted the C: drive until TrustedInstaller blocked it at C:\Windows with over 500,000 access-denied errors, after which the agent reported that the clean-up had succeeded. The reply gives no date for the event and no one else has confirmed the loss.
