What is a VBK file?
A .VBK file usually contains a VitalSource Digital Textbook. VitalSource Technologies uses this format to distribute educational eBooks securely. Internally, these files often store page data as JPG or PNG images. However, a .VBK file can also be a Veeam Backup File. Veeam Software creates these files to store full virtual machine backups. Because .VBK has multiple possible meanings, we recommend using viewer.online/vbk to identify the actual format of your file.
How to open VBK files?
If your file is an eBook, you can open it with VitalSource Bookshelf on a computer or mobile device. If your file is a backup archive, you must use Veeam Backup & Replication to extract the system data. viewer.online/vbk analyzes .VBK files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Always check the size of your .VBK file. A Veeam Backup File is typically very large because it holds entire computer systems. A digital textbook is much smaller. Do not rename the file extension to force a program to read it, as this will not change the data inside. If your eBook reader fails to open the file, it might be protected by Digital Rights Management (DRM) or it might be a backup file instead.
Software and tools
Students use VitalSource Bookshelf to read textbook files. System administrators use Veeam Backup & Replication to protect and restore server data. In rare cases, the file might also be an older Nortel voice message.
Summary
Because .VBK files use the known JPG format, viewer.online/vbk can safely open and display them online, eliminating compatibility problems.
