What is HPL file?
The file in the HPL format belongs to the Vector Image Files category. It was designed by Hewlett-Packard. Additionally, the Vector Image Files category contains 138 of other files. HP-GL Plotter Format appears on 2 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Mac OS, Windows. The TurboCAD application is recommended to open the file. It was released by IMSI/Design, LLC.. This file type can also be opened by 5 other programs. You can use PaintShop Pro, XnView, CADintosh in case TurboCAD cannot be used.
How to open HPL file?
The most common problem when using HP-GL Plotter Format is that a specific HPL is not associated with the program. Thus, when you open HPL, the program selection wizard or some other program starts. How to solve such a problem?
The first thing you should do is just "doubleclick" on the HPL 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 TurboCAD
In this case, you should first verify that the TurboCAD application is installed on the computer. The easiest method is to use the system search engine by entering the program name TurboCAD in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support HPL files.
Programs to open HPL file
Remember to download programs supporting HPL files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of TurboCAD with HPL files
If, despite the installed application, the HPL file does not start in the TurboCAD application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the HPL file with the TurboCAD application.
Step 3. Update TurboCAD to the latest version
If, despite the association of the TurboCAD program with the HP-GL Plotter Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the IMSI/Design, LLC. page and install.
Step 4. Check for the following problems with the HPL file
The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:
The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the HPL file. Downloading the file again should fix the problem.
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. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file HPL or the program directory. However, remember that not every infected HPL file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the HPL 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 this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged HPL files. The easiest way to restore the file is from a backup or by contacting Hewlett-Packard, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file HPL 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 of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the HPL file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the HPL file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
