Opening 003 files

Did your computer fail to open a 003 file? We explain what 003 files are and recommend software that we know can open or convert your 003 files.

What is a 003 file?

Files that contain the .003 file extension are split archive files. These files are created by archive and compression applications, such as the WinRar or WinZip programs. These software programs are used to take large files and collections of files and compress them into a single archive folder. The resulting archives can then be split into multiple volumes using software like HJSplit or SplitJoin.

When an archive file is split, each volume of the archive is assigned a numbered file suffix, usually in sequence. Files with the .003 extension are usually the third volume of the split file archive. Before you can open the .003 file, you will need to merge all of the archive volumes together.

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.
