The Local Temp folder is a place on your computer where Windows and programs store temporary files. These files are created while you install software, open documents, browse the internet, or run other tasks. They can include things like cached data, setup files, temporary backups, or parts of files you're working on. In Windows 10 and 11, the Temp folder is mainly found in two locations:
🔶C:\Users\[YourUsername]\AppData\Local\Temp
However, if the Local Temp folder keeps filling up, you might start to wonder whether it's safe to delete it in Windows 10 and 11. Yes, it's safe to delete files in the Local Temp folder on both Windows 10 and 11. These files are meant to be temporary and are usually created during software installations, updates, or when programs run. Over time, they can build up and take up a lot of space, especially on your C drive.
