What are PART1 files and how to open them

Are you having problems opening a PART1 file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a PART1 file?

Files with the .part1 extension are most commonly associated with the PeaZip file archiving software. PeaZip can be used to take a large batch of files and compile them into a single file archive. This archive can then be split into separate volumes to make it easier to distribute the files online or to allow for storage of the archive across multiple disks. When the archive is split into separate volumes, each volume is given its own file extension. The .part1 file extension is given to the first volume of the archive.

The .part1 extension is also used for NetObjects Fusion system files.

How to open PART1 files

Important: Different programs may use files with the PART1 file extension for different purposes, so unless you are sure which format your PART1 file is, you may need to try a few different programs.
