The 003 file extension is associated with several archivers or compression tools, which are using, or did use in the past, the 003 file extension for its multi-volume files or archives, such as Winrar (see rar) or 7-Zip (see 003).
The general file sequence is 001, 002, 003, etc. and you will need all parts of the multi-volume archive to successfully extract the content.
To open or extract the content of the multi-volume archive just put all the parts in same directory and extract the first part in your favourite archiver, such as WinRar or 7-Zip.
Only complete archive can be converted in to another archive or compression format. The easiest way how to convert complete multi-volume archive is to decompress the archive with the use of supported archiving or compression tool and repack the content with another compression or archive application of your choice.

SplitJoin, HJSplit, Splitter, and file-management software such as Total Commander can create or work with numbered file parts. In a split set, the extension numbers identify the pieces in sequence; a 003 file is the segment numbered 003. Parts in a set are commonly numbered 001, 002, 003, and so on.
The 003 part usually needs to be joined with the other parts to restore the original file before it can be opened or used. The restored file may be an archive, a backup, or another type of file, including a large game data file used by some computer games. These utilities are available for Microsoft Windows.
Keep all parts of the set together, then use a joining utility to reconstruct the original file. These Windows programs are associated with split files:
A 003 part cannot usually be converted by itself. First join all the parts to restore the original file; if it is an archive, use suitable archive software to unpack or repack it in another format. Conversion of other restored file types depends on the application that supports that type.
