What is HGR file?

The file with the extension HGR is the Raster Image Files file type. Additionally, the Raster Image Files category contains 522 of other files. Apple II Bitmap Image Format is most often found on 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is RECOIL. This was created by Piotr Fusik and Adrian Matoga.

How to open HGR file?

The most common problem when using Apple II Bitmap Image Format is that a specific HGR is not associated with the program. This causes the file HGR to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the HGR 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 RECOIL

An often overlooked issue is to make sure that RECOIL is installed on the computer. The easiest method is to use the system search engine by entering the program name RECOIL in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file HGR with RECOIL. Below is a list of programs that support the file HGR.

Programs to open HGR file

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

Step 2. Create association of RECOIL with HGR files

If the application is or has been freshly installed, but the HGR file still does not use the RECOIL 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. Using the "Change" button we can select the desired program. 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. The "always use the selected program ..." field will set the RECOIL application as the default for handling the HGR file.

Step 3. Update RECOIL to the latest version

If, despite the association of the RECOIL program with the Apple II Bitmap Image 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 Piotr Fusik and Adrian Matoga website or update the program from the application.

Step 4. Check for the following problems with the HGR 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 HGR files downloaded from the Internet in case the download did not finish properly. 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. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the HGR file that we want to open. Sometimes virus-infected HGR files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the HGR 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. Sometimes the program itself has options to repair the most popular HGR file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
The program can also signal the fact of encryption. The encrypted HGR 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. It is best to move HGR to a different directory.
This can happen on a file that does not support multiple access. In this case, the HGR 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 HGR to close. Some anti-virus or backup software may occupy the HGR file for a certain period of time. If the problem persists, restart the machine.
