What is a part file?

A part file is a temporary file that is created by a program when it is in the process of downloading or saving a larger file. Part files typically have a .part extension and contain only a portion of the complete file.

Part files are commonly used by web browsers, file-sharing programs, and download managers to store the data that has been downloaded so far. This allows the user to resume the download at a later time without having to start from the beginning.

Once the complete file has been downloaded, the part file is merged with the rest of the data to create the final file. If the download is interrupted or the file is not fully downloaded, the part file can be deleted without affecting the original file.

Overall, part files are a useful tool for managing large downloads and ensuring that data is not lost if the download is interrupted.
