A .qp03 file is a numbered part of a compressed archive created by qpress.
It is typically the third part of a split qpress archive and is used together with the other numbered parts.

qpress is a multiplatform file archiver that compresses files into qpress archives. The .qp03 file extension typically identifies the third numbered segment when an archive has been split into multiple files.
A .qp03 file is therefore not normally a complete, independent archive. The complete compressed data is distributed across the numbered parts, which must be kept together for qpress to reassemble and extract the archive. The .qp03 file is a qpress-specific archive part rather than a general-purpose archive format.
Keep the .qp03 file with all the other numbered parts of the same qpress archive, including the first part. Open or extract the complete set with qpress, which is available on multiple platforms. Opening the .qp03 file by itself will generally not provide the complete archive.
A .qp03 file cannot normally be converted by itself because it is only one part of a split qpress archive. Use qpress to reassemble and extract all the parts first.
The extracted files can then be compressed into another archive format with suitable archiving software.
