Opening PART1 files

Did your computer fail to open a PART1 file? We explain what PART1 files are and recommend software that we know can open or convert your PART1 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.

Software that will open, convert or fix PART1 files

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
