Notes about the SPWB file extension:



Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The SPWB file type is primarily associated with 'ShadowProtect' by StorageCraft Technology Corporation.

StorageCraft ShadowProtect Server provides disaster recovery, system migration and data protection for Windows servers.

ShadowProtect IT Edition uses three types of files with the following file type extensions, .SPF, .SPI and .SP(number). Each of these types of files is described below...

  • SPF are full image files. These are the files created when making images using ShadowProtect IT Edition.
  • SPI are incremental image files. These files are created when an image file is mounted as writeable and the changes made to the image are saved as an incremental image.
  • SP(number) are images that belong to a spanned image set. Spanned image sets are made by breaking the image into smaller sizes for increased manageability. For example, breaking an image into files to be saved onto multiple CDs. The number represents the sequence the file represents within the spanned image set.

When images are mounted as writeable volumes, any writes made to the volume are stored in a temporary buffer file (.SPWB). After dismount, the contents of this file can be converted into an incremental (.SPI) image which contains all of the changes/writes made to the volume.
