Extract text from installer archives (FIZ)
To convert FIZ archives to another format, you need Flexera InstallShield or other Compressed software.
To convert other file formats to the "Installer & Inventory Archive" file type, you need software like Flexera InstallShield or a similar tool.
A .fiz file typically serves one of two distinct, highly specialized functions. Primarily, it operates as a compressed fridge inventory archive managed by specialized software linked to Foundry. Under the hood, this variant uses a hybrid structure - combining legacy Adobe Flash technology with standard ZIP compression to store structured inventory records, such as item quantities, configurations, and product metadata. Alternatively, a .fiz file can function as a Flexible Installation Package created by Flexera InstallShield (now managed by Revenera). In this scenario, it acts as a proprietary, compressed bundle containing the software routines and binaries needed for a Windows application deployment.
Dealing with .fiz files in modern environments is notoriously frustrating. The inventory variant relies heavily on deprecated Flash technology, meaning modern web browsers and mobile operating systems will flatly refuse to open it. It is a closed, proprietary container that tightly locks away your data. The InstallShield variant is similarly opaque; it is designed to be executed strictly by an installer engine, not browsed by a user, making it impossible to directly extract a single driver or asset without launching the full installation process. Because these files share the exact same extension but have completely different internal architectures, standard online converters almost always fail to process them.
The most practical workaround is to extract the underlying contents rather than attempting a direct visual conversion. We recommend converting or extracting the .fiz file into a standard ZIP archive, which allows you to bypass the proprietary wrapper. From there, embedded database records can often be recovered as XML or TXT, and media components as SWF or PNG.
While this file format is difficult to open or convert due to its reliance on outdated and closed software ecosystems, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is - if our analysis detects a supported underlying or embedded format like a standard ZIP structure, viewing or conversion may still be possible.
Convert.Guru analyzes your FIZ file, detects the exact format, and lets you read the text inside.
Users also converted TEST, TW and DPT files.

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 FIZ converter.
