Hi Cursor team,

I noticed that Cursor suddenly consumed more than 100 GB of disk space inside the globalStorage directory on my Windows machine.

The affected directory is:

C:\Users\LENOVO\AppData\Roaming\Cursor\User\globalStorage

Current file sizes:

  • state.vscdb: ~77.5 GB
  • state.vscdb.backup: ~22.9 GB
  • state.vscdb-wal: ~89 MB
  • Total Cursor globalStorage: ~100.5 GB

I did not intentionally store this amount of data in Cursor, and I only noticed the issue after checking my disk usage.

Expected behavior

state.vscdb and Cursor’s globalStorage should remain at a reasonable size and should not continuously grow to tens of gigabytes during normal usage.

Actual behavior

The database appears to have grown unexpectedly until Cursor was consuming more than 100 GB of local storage.

Environment

  • OS: Windows 11
  • Cursor: [insert Cursor version here]
  • Storage location: %APPDATA%\Cursor\User\globalStorage

I have attached a screenshot showing the disk usage.

Could you please confirm:

  1. What could cause state.vscdb to grow to this size?
  2. Is this related to chat history, AI agent/composer data, checkpoints, extensions, or another Cursor feature?
  3. Is it safe to delete or recreate state.vscdb and state.vscdb.backup without losing important projects/settings?
  4. Is there currently any automatic cleanup or size limit for this database?
  5. Is there any diagnostic information I can provide to help identify what is filling the database?

This seems potentially serious because the database can consume a very large amount of disk space without an obvious warning.

Thanks.
