Tips to open GPT file
Can't open the GPT file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open GPT files as well as a list of programs that support GPT files.
GPT file extension
The GPT file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the GPT files. Below is a summary of the number of programs that support and open the GPT file on each system platform.
What is GPT file?
The file with the extension GPT is the 3D Image Files file type. Additionally, the 3D Image Files category contains 622 of other files. Gerber Top Pad Master 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 Altium Designer. This was created by Altium Limited..
How to open GPT file?
The most common problem when using Gerber Top Pad Master is that a specific GPT is not associated with the program. This is manifested by the fact that GPT files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the GPT 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 Altium Designer
The first step is to check if the computer has the Altium Designer program installed. To do this, enter the name Altium Designer into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open GPT files.
Programs to open GPT file
Remember to download programs supporting GPT files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Altium Designer with GPT files
However, it may happen that the application itself does not cause the GPT file to open in the Altium Designer application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the GPT file with the Altium Designer application.
Step 3. Update Altium Designer to the latest version
The fault may also lie with the Altium Designer program, it is possible that Gerber Top Pad Master requires a newer version of the program. In this case, use the Altium Limited. website or update the program from the application.
Step 4. Check for the following problems with the GPT file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
The GPT file may be unusually small compared to the original file. This is most often caused by a problem while downloading the GPT file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file GPT or the program directory. As a result of the scan, sometimes it is not possible to recover GPT 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 GPT 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. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair GPT file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program can also signal the fact of encryption. The encrypted file GPT 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.
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. If possible, you can try to move the GPT file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the GPT file for a certain period of time. If nothing helps, please reset the device.
