Exposing a proprietary disk file to a hypervisor as a native hypervisor disk file

One or more non-transitory computer-readable media storing one or more programs that are configured, when executed, to cause one or more processors to perform a method of exposing a proprietary disk file to a hypervisor as a native hypervisor disk file, the method comprising:

• creating a plugin file corresponding to a proprietary disk file, the proprietary disk file having a proprietary file format;
• intercepting, using a file system filter driver that sits between a hypervisor and a file system where the plugin file is stored, a file open request directed to the plugin file;
• determining that the plugin file has a plugin file format;
• responding, using the file system filter driver, to the file open request with a report that the plugin file was opened successfully;
• intercepting, using the file system filter driver, file read requests directed to the plugin file;
• and
• responding, using the file system filter driver, to each of the file read requests with data gathered from the plugin file and/or the proprietary disk file, the data being structured to cause the data to appear to be gathered from a native hypervisor disk file due to being formatted in a native file format of the hypervisor.
