ZipSplitter for Microsoft Windows divides a compressed archive into multiple files, making it easier to store or transfer. The .s03 file contains one volume in that set and represents part 4 of the split archive.
The other volume files are required to reconstruct or extract the original archive. The files should retain their original names and be kept together; changing the extension or removing a volume can prevent ZipSplitter from processing the set.
This is a utility-specific split-archive file rather than a standalone archive format. It remains usable with ZipSplitter on Microsoft Windows, but the file cannot normally be used independently of the other volumes.
Place the .s03 file in the same folder as all the other parts of its ZipSplitter archive. Open the corresponding first archive file in ZipSplitter on Microsoft Windows and use the program to reconstruct or extract the contents.
Opening the .s03 file by itself will not normally work because it is only one volume of the complete archive.
An .s03 volume cannot be meaningfully converted on its own. First use ZipSplitter with every volume present to reconstruct or extract the original archive.
After extraction, the resulting files can be added to a standard archive format with a suitable archiving program. The original split set can also be recreated with ZipSplitter when multi-volume output is required.
