Extract text from Compressed archives (SZP)
To convert SZP Archives to another format, you need Siemens SIZER or other Compressed software.
To convert other file formats to the "Proprietary Compressed Archive" file type, you need software like Siemens SIZER or a similar tool.
The .SZP file extension has several distinct uses, making it frustratingly vague for standard users. Its most common application is as a compressed Nintendo game archive utilized in titles like Luigi's Mansion. These files rely on the proprietary Yay0 compression format to store game assets. Alternatively, a .SZP file can be a drive engineering project file created by Siemens SIZER, which structurally relies on the Microsoft Compound file format. Another common variant is a zipped audio session file exported by Avid Pro Tools, functionally identical to a standard ZIP archive.
The primary disadvantage of a .SZP file is its extreme lack of standardisation. Because the extension is shared across highly specialised, disconnected industries (gaming, electrical engineering, and audio production), operating systems cannot natively assign a default program to open it. Standard converters usually fail because they do not know which data structure (Yay0, Microsoft Compound, or ZIP) is inside. For Pro Tools users, the file is a disguised ZIP, but for Siemens users, it requires proprietary desktop software to parse the drive parameters.
If you need to access the contents, your best target formats depend on the origin. For Pro Tools files, renaming the extension to ZIP allows you to extract the raw audio assets. For Siemens engineering files, you typically need to export the data directly from the SIZER software to a PDF report or XLSX spreadsheet. Nintendo Yay0 archives require specialised modding tools to decompress into standard BIN or DAT files.
Converting .SZP files directly is difficult because these are closed formats designed for specific software environments. Often, only the original software can properly read or export the data. We will inspect the binary signature to tell you whether it is a ZIP file, a Microsoft Compound document, or a proprietary game archive, and convert it if our analysis detects a supported embedded format.
Convert.Guru analyzes your SZP file, detects the exact format, and lets you read the text inside.
Users also converted SSP, MT and SSG files.
If you want to convert SZP file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use Siemens SIZER or similar software from the "Compressed Data Archive Storage" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to SZP, try Siemens SIZER or another comparable tool in the "Compressed Data Archive Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SZP converter.
