What is a ULAW file?
ULAW is an extension characteristic of files related to PCM telecommunications systems. ULAW is a format that allows you to store audio data. It is a monophonic sound generated most often with 8-bit PCM (Pulse-Code Modulation) coding. It is a method of representing an analog signal in a digital way.
ULAW files were mainly known in North America and Japan. Currently, this format is rare and is considered obsolete.

How to open ULAW files
If you cannot open the ULAW file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports ULAW among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the ULAW file can be found in the table. Now just download and install the appropriate application.
Possible problems with the ULAW format files
The inability to open and operate the ULAW file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Raw CCITT/ITU G.711 US Telephony Audio Format file. Below is a list of possible problems.
- Corruption of a ULAW file which is being opened
- Incorrect links to the ULAW file in registry entries.
- Accidental deletion of the description of the ULAW from the Windows registry
- Incomplete installation of an application that supports the ULAW format
- The ULAW file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the ULAW file.
- Drivers of equipment used by the computer to open a ULAW file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the ULAW file should operate with your programs without any problem. If the problem with the ULAW file has not been solved, it may be due to the fact that in this case there is also another rare problem with the ULAW file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.ULAW) you have two ways to do it. The first and the easiest one is to right-click on the selected ULAW file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the ULAW file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. ULAW) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
