Abstract
Using a block-based region file to extend a composite image (CIM). A device determines to replace a first file with a second file within a filesystem volume of the CIM. The device identifies a first file definition within CIM metadata, which defines the first data of the first file as including a first data block of a first CIM region file comprising equally-sized data blocks. The device extends the CIM to include the second file. The extension includes adding a second region file comprising equally-sized data blocks to the CIM, including writing a portion of data from the second file into a second data block of the second region file. The extension also includes writing a second file definition to the CIM metadata, which defines the second data of the second file as including the first data block and the second data block.
