The ATC file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the ATC files. Below is a summary of the number of programs that support and open the ATC file on each system platform.
What is ATC file?
The ATC file has been categorized as Settings Files. The author of this format is Autodesk. Settings Files consists of 1305 similar files. AutoCAD Catalog Format is supported by 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The main program that supports this format is AutoCAD. This was created by Autodesk, Inc.. This file type can also be opened by 2 other programs. You can use AutoCAD Civil 3D, AutoCAD LT in case AutoCAD cannot be used.
How to open ATC file?
The most common problem when using AutoCAD Catalog Format is that a specific ATC is not associated with the program. This is manifested by the fact that ATC files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the ATC 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. This can be achieved by typing AutoCAD 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 ATC files.
Programs to open ATC file
Remember to download programs supporting ATC files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of AutoCAD with ATC files
If the application is or has been freshly installed, but the ATC file still does not use the AutoCAD program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. 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 ATC file with the AutoCAD program.
Step 3. Update AutoCAD to the latest version
If, despite the association of the AutoCAD program with the AutoCAD Catalog Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Autodesk, Inc. website or update the program from the application.
Step 4. Check for the following problems with the ATC file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
The ATC file may be unusually small compared to the original file. This is most often caused by a problem while downloading the ATC file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the ATC file that we want to open. As a result of the scan, sometimes it is not possible to recover ATC files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the ATC files changes over time. 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 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 ATC file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Autodesk
The program can also signal the fact of encryption. The encrypted ATC 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the ATC file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the ATC file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file ATC to close. However, some background programs may block the ATC file while scanning. If this does not work either, restart the device.
