What is an MSAV file

MSAV files mostly belong to Avorion. MSAV files are mainly used to store game save data.
some of these files are Avorion game save files that use the zlib compression method to contain information like player progress, game settings, and world state.
A minor set of MSAV files are linked to antivirus operations, where they serve as Microsoft Antivirus scan files created by the MSAVLM.EXE utility.
When handling a MSAV file, consider the following points:

Back up the file before any modification to avoid loss of game progress.

If the file is a game save, open it with the game or a dedicated game save editor.

For antivirus scan files, use the proper antivirus software to interpret the data.

If you need to view the contents directly, a hex editor or a tool that can decompress zlib data may help.

Programs that open and convert MSAV files:

Avorion
See the previous paragraphs to learn more about the main application. MSAV files are often referred to as Avorion games because this type of file is primarily created or used by this software.
Avorion or Microsoft Antivirus
The *.MSAV file extension is primarily associated with Microsoft Antivirus, a legacy component of older Windows operating systems. These files likely contained definitions and other data used by the scanning engine. Given the age of this software, encountering *.MSAV files is uncommon on modern systems. Avorion, a space-exploration and building game, also uses the *.MSAV extension for its game save files. These files store the player's progress, ship designs, and other game-related data. The internal structure of Avorion's *.MSAV files utilizes zlib compression. This file format is classified as Game Data or Legacy Antivirus Data.

MSAV file extension format:

A file format defines how the data in the file is structured. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. File extension, signature and file format must match; otherwise errors will occur when the file is opened. If there are problems opening a file, you must first determine the file format used. Our evaluation of the MSAV files is as follows:

The MSAV file extension is not common and is primarily used by a single program. The two most popular formats are as follows:

98% of all MSAV files are using the well-known zlib file format to store the data. Zlib is a compressed archive file format that supports several different data compression algorithms. zlib is also a crucial component of many software platforms, including Linux, macOS, and iOS. If you open these files in a text editor, you will see only illegible characters. A typical file size is 32 KB. The file type was developed only in the last few years. Files like these are about sector, serpulo, backup and erekir.

The remaining 2% of all MSAV files are different files with different signatures. If you want to find out what your MSAV file contains, drag and drop it onto this page.
