Lots of weird problems happen if you’re low on disk space–programs randomly fail, the operating system can seem unreliable, and you might lose work because you can’t save it.
Just like Windows XP, Windows Vista includes the Disk Cleanup Wizard. To use the Disk Cleanup Wizard to free up space, follow these steps:
- Click Start, and then click Computer.
- Right-click the drive you need to improve free space on, and then click Properties.
- On the General tab, click Disk Cleanup.
- On the Disk Cleanup Options page, click either My files only or Files from all users on this computer. You’ll clean up more disk space if you work with files from all users, but you need administrative credentials. If prompted, provide administrative credentials.
- After a few seconds, the Disk Cleanup page appears. Scroll through the available options, and select the check box for anything you’re ready to delete. If you’re not sure, leave it.
You’re pretty safe removing the following files:
- Downloaded Program Files
- Temporary Internet Files
- Microsoft Error Reporting Temporary Files
- System error memory dump files
- System error minidump files
- Temporary files (close your programs first!)
- Per user archived Windows Error Reporting files
- Per user queued Windows Error Reporting files (hey, it’ll probably crash again in the future anyway)
- System archived Windows Error Reporting files
- System queued Windows Error Reporting files
