size NumContainers Path Sets the number of containers available to the Transactional
Resource Manager. You can use this option to manually return hard drive space to the system
after performing a number of file system object changes.
Sparse
Some applications create large files that contain mostly zeros. For example, an application may create
a large cache to hold temporary data. Sparse file management compresses these files smaller than
standard compression can. For a discussion of sparse files, see the ???Understanding Sparse Files??? sidebar.
This mode helps you manage sparse files and uses the following syntax:
FSUtil Sparse [setflag Filename] [queryflag Filename]
[queryrange Filename] [setrange Filename Offset Length]
The following list describes each of the command line arguments.
Filename Specifies the file to manage.
Offset Defines the beginning of a sparse range.
Length Determines the number of bytes in the sparse range.
setflag Adds a sparse attribute to the file to mark it as a sparse file.
queryflag Displays status information as to the state of the sparse flag (attribute).
Hard Drives as Databases
Hard drives have always been a kind of database, but operating systems typically don??™t treat them that
way.
