How to open CUS file?
The main problem with AutoCAD Custom Dictionary Format is that the CUS file is incorrectly associated with programs. Thus, when you open CUS, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the CUS 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 AutoCAD
An often overlooked issue is to make sure that AutoCAD is installed on the computer. To do this, enter the name AutoCAD into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file CUS.
Programs to open CUS file
Remember to download programs supporting CUS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of AutoCAD with CUS files
However, it may happen that the application itself does not cause the CUS file to open in the AutoCAD application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the CUS file with the AutoCAD program.
Step 3. Update AutoCAD to the latest version
If, however, after binding AutoCAD with AutoCAD Custom Dictionary Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Autodesk, Inc. page and install.
Step 4. Check for the following problems with the CUS file
The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:
Very often, the file may be size 0 or incomplete. This suggests truncating the CUS file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our CUS file. However, remember that not every infected CUS file can be recovered, so it is important to take care of regular backups.
Older version of CUS file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular CUS file corruption. You can restore the file from a backup or use Autodesk help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CUS files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. Copying the CUS file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the CUS file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the CUS file while scanning. If this does not work either, restart the device.
