The OPML file is supported on 4 operating systems. Depending on your operating system, you may need different software to handle the OPML files. Below is a summary of the number of programs that support and open the OPML file on each system platform.
What is OPML file?
The file in the OPML format belongs to the Web Files category. Additionally, the Web Files category contains 303 of other files. Outline Processor Markup Language Format is supported by 4 operating systems. The file will work on , Linux, Mac OS, Windows systems, unfortunately not on others. The main program that supports this format is OmniOutliner. This was created by The Omni Group. Alternatively, you can use 17 other programs. The ConceptDraw MINDMAP, OPML Editor, Tkoutline, Natara Bonsai programs will also handle the file when the OmniOutliner program does not fulfill its role.
How to open OPML file?
The most common problem when using Outline Processor Markup Language Format is that a specific OPML is not associated with the program. Thus, when you open OPML, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the OPML 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 OmniOutliner
The first step is to check if the computer has the OmniOutliner program installed. This can be achieved by typing OmniOutliner into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file OPML.
Programs to open OPML file
Remember to download programs supporting OPML files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of OmniOutliner with OPML files
If the application is or has been freshly installed, but the OPML file still does not use the OmniOutliner 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 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. The "always use the selected program ..." field will set the OmniOutliner application as the default for handling the OPML file.
Step 3. Update OmniOutliner to the latest version
If, despite the association of the OmniOutliner program with the Outline Processor Markup Language 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 The Omni Group page and install.
Step 4. Check for the following problems with the OPML 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:
Very often, the file may be size 0 or incomplete. This suggests truncating the OPML file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the OPML file that we want to open. However, remember that not every infected OPML 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 OPML 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. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair OPML 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 OPML 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. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the OPML file to another location.
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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the OPML file for a certain period of time. If the problem persists, restart the machine.
