What is a UMS file?

UMS files mostly belong to UMS Viewer.

An UMS file is used in different systems and applications. It may represent a unify message store or contain settings and data lists for hardware components.
Usage examples include:

• Unified Message Store: Files of this type store organized messages, often encoded in UTF-16 (LE). They are designed to be read by specific software like the UMS Viewer.
• Printer Parts List: In another implementation, an UMS file holds details such as a parts list for Ricoh printers. These files are managed with the RICOH UMS Editor, and more details can be found on the Ricoh website.

FilExt.com tip: Opening these files with a generic text editor may display encoded content. It is best to use the dedicated application based on the file's purpose.

How to open a UMS file

You need a suitable software like UMS Viewer to open a UMS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your UMS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a UMS file directly in the browser:. Just drag the file onto this browser window and drop it.

UMS file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So you need a detailed analysis of a file to find out the format and the associated program. Our examination of the UMS files comes to the following conclusion:

The UMS file extension is not common and has no uniform or dominant file format. The file formats most commonly found in UMS files are:

• 15% of all UMS files internally utilize the UTF-16 (LE) file format. UTF-16 (LE) is an character encoding system for Unicode. UTF-16 files can be viewed in any modern text editor. These files start with the two bytes FF FE, the so called byte order mark (BOM). They consist of unreadable binary data. The files are on average 180 bytes in size and range from 180 bytes to 180 bytes. The following keywords are characteristic: V@&f^x and JD<D. Some examples of file names are Busy.UMS.
• 8% of all UMS files use the same file format, which can be identified by the letters "03 32 2E 33" at the beginning. These files are not plain text files, so they also contain binary data. The files are often between 6 MB and 18 MB in size.

The remaining 77% of all UMS files are different files with different signatures, frequently e.g. Unreal. Files like these are sometimes linked to labels, onlinehistory or statement. If you want to find out what your UMS file contains, drag and drop it onto this page.
