How to open ULW file?

The most common problem when using U-Law Audio Format is that a specific ULW is not associated with the program. This is manifested by the fact that ULW files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ULW file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install NCH Switch

The first step is to check if the computer has the NCH Switch program installed. This can be achieved by typing NCH Switch into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support ULW files.

Programs to open ULW file

Remember to download programs supporting ULW files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of NCH Switch with ULW files

However, it may happen that the application itself does not cause the ULW file to open in the NCH Switch application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the NCH Switch application as the default for handling the ULW file.

Step 3. Update NCH Switch to the latest version

If, however, after binding NCH Switch with U-Law Audio Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the ULW file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to ULW files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the ULW file that we want to open. As a result of the scan, sometimes it is not possible to recover ULW files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the ULW file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular ULW file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file ULW except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the ULW file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file ULW to close. However, some background programs may block the ULW file while scanning. If this does not work either, restart the device.
