# Windows C: Drive Space Maintenance Guide
Windows workstations have a 2 GB per-user quota on the C: drive. If your folder exceeds this limit, Windows and installed applications may not work correctly.
Use TreeSize to find large files in your user folder and free up space.
## 1. Open TreeSize
Open the Windows search menu, type `TreeSize`, and select the app.
## 2. Scan the C: drive
In TreeSize, click **Select Directory**. Then select **Local Disk (C:)**.
## 3. Review Your User Folder
After the scan finishes, expand `C:\Users` and open your user folder.
Review the largest folders first. Delete files you no longer need, or move them to another location such as the `F:` drive.
