Free Up Disk Space on Your Computer
Optimal computer performance requires sufficient available disk space. Cornell IT (CIT) suggests that your computer should at least have 25 GB of free space at all times. During normal operation, your computer uses its available free space as an extension of memory (RAM). More free disk spaces means a more responsive computer. Moreover, security updates that prevent your computer from evolving threats require free space to install.
