Programs to open VELLUM file

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

Step 2. Create association of Vellum with VELLUM files

If the application is or has been freshly installed, but the VELLUM file still does not use the Vellum 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. 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 VELLUM file with the Vellum application.

Step 3. Update Vellum to the latest version

The fault may also lie with the Vellum program, it is possible that Vellum E-book Project Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the 180g website and install the latest version.

Step 4. Check for the following problems with the VELLUM 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 VELLUM file may be unusually small compared to the original file. Usually this applies to VELLUM files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. 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 VELLUM or the program directory. As a result of the scan, sometimes it is not possible to recover VELLUM files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of VELLUM file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair VELLUM file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted VELLUM 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 VELLUM file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the VELLUM file again. Some anti-virus or backup software may occupy the VELLUM file for a certain period of time. If this does not work either, restart the device.
