What is OH file?
The file in the OH format belongs to the Document Files category. Document Files consists of 574 similar files. DrillAssistant List appears on 1 operating systems as a functional file. 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 DrillAssistant. This was created by Efka-Soft.
How to open OH file?
The main problem with DrillAssistant List is that the OH file is incorrectly associated with programs. This is manifested by the fact that OH 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 OH 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 DrillAssistant
An often overlooked issue is to make sure that DrillAssistant is installed on the computer. To do this, enter the name DrillAssistant into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open OH files.
Programs to open OH file
Remember to download programs supporting OH files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of DrillAssistant with OH files
If the application is or has been freshly installed, but the OH file still does not use the DrillAssistant program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the OH file with the DrillAssistant program.
Step 3. Update DrillAssistant to the latest version
The fault may also lie with the DrillAssistant program, it is possible that DrillAssistant List requires a newer version of the program. In this case, use the Efka-Soft website or update the program from the application.
Step 4. Check for the following problems with the OH 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:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the OH 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. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our OH file. Sometimes virus-infected OH files cannot be recovered, so make a backup in advance.
Older version of OH 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. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair OH file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted OH files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move OH to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the OH file again. 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.
