Step 1. Install NoteTab Pro

Programs to open OTL file
Remember to download programs supporting OTL files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of NoteTab Pro with OTL files
If the application is or has been freshly installed, but the OTL file still does not use the NoteTab Pro 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. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the OTL file with the NoteTab Pro application.
Step 3. Update NoteTab Pro to the latest version
If, however, after binding NoteTab Pro with NoteTab Outline Format there were still problems, you should update the program to the latest version.
Step 4. Check for the following problems with the OTL file
Of course, it may happen that despite the above steps, the file still does not work. 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 OTL file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our OTL file. Sometimes virus-infected OTL 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 OTL files changes over time. These problems are known and are often very easy to fix using the software developers's website.
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 OTL file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted OTL 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.
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 OTL file to another location will fix the problem.
This problem usually affects more complex files. In this case, the OTL file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the OTL file again. Some anti-virus or backup software may occupy the OTL file for a certain period of time. If the problem persists, restart the machine.
