The PART00000 file extension is primarily known to associate with "Partial Download" files. When you download files, particularly large ones, the download process might get interrupted due to various reasons such as network issues or system crashes. In such cases, browsers like Chrome or Firefox create PART files where the data is saved until the download is resumed or completed. The 'PART00000' file can also be created by some mail servers or clients. In the following sections, we will discuss in detail how to handle these formats.

Partial Download Files

The primary use of PART00000 files is associated with the interrupted downloads. In this case, when you initiate a download, your browser starts creating a PART file, and this file grows as more bytes of the file are being downloaded. If the download gets interrupted due to any reason, you will be left with a PART file. Once download is resumed and completed successfully, the PART file is automatically converted to the format of the downloaded file.(source)

Mailserver Files

PIRIFORM Defraggler uses the PART00000 file type associated with mail servers or clients. It creates these files in the defragmentation process to move blocks of data. While these files, like any system files, should not be opened manually, they are inherently harmless. They should automatically delete themselves once the defragmentation process is completed if all goes according to plan. If not, they may be deleted manually, though this should probably be avoided unless necessary. (source)
