Identify the Source: A .UL file often comes from legacy telephony systems or audio engineers, which suggests it may be a uLAW Audio File.
Check the Header: Inspect the first bytes in a hex viewer or text editor to find clues:
- No standard magic bytes often implies raw audio data.
- "PK" indicates a zipped archive.
- Readable XML/JSON suggests a configuration file.
Use the Original Software: The original program is usually required; try audio tools like Audacity, VLC Media Player, or SoX. If uncertain, ask the sender.
Use this Webpage: Drag and drop the file into our viewer to detect the format, extract readable text or metadata, and preview it when possible.

UL file format details:

UL is not a common file extension and covers a large number of different file formats. The two most popular formats are as follows:

7% of all UL files are based on the popular XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The contents of these files are easily readable with a text editor. UL files can be up to 120 KB in size, but are often around 39 KB - 120 KB. The files contain the following words: <?xml version="1.0" encoding="utf-8"?>, Service Pack 1, Windows 7, language, lastupdate, platform, product, servicepack="Service Pack and updatelist. The file name windows-7-sp1-x64-enu.ul or Windows_7_SP1_Updates_x86.ul is typical for these files. Files like these are about windows and updates.
7% of all UL files store the data in 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). The contents of these files cannot be read by a human; only a computer program can interpret the data. The file size is in the range of 5 KB to 33 KB.

All other UL files (86%) have different formats, often e.g. COMPOVIC. Tagged as compensation, devdt, standard, english or data. Just click the "Choose your .ul file to analyze" button on this page to find out what your UL file is.
