What Are Temporary Files?

Temporary files are short-lived files generated by the Windows operating system and third-party software during tasks such as:

• Extracting .zip or installer files
• Streaming media or downloading software updates
• Storing unsaved auto-recovery buffers in office and editing tools
• Holding application crash logs and dump records

When applications close normally, they are expected to delete their own temporary files. However, crashes, abrupt shutdowns, and poor application design often leave gigabytes of orphaned data behind.
