setzerodata Offset=StartRange Length=RangeLength Filename Changes the data bits
within a file to 0. This is an excellent method of clearing a file before deleting it for security
reasons (deleting a file retains the data on disk; Windows only removes the directory entries,
making the file recoverable). The start range determines the starting point within the file for
writing zeros. The start of the file is 0, but you can use any range up to the size of the file in bytes.
The range length determines how many zeros to write. This value must be less than or equal to
the length of the file minus the start range value.
createnew Filename Length Creates a new file that FSUtil fills with zeros. You must include
a filename and the length of the file. Because these files are zeroed, they make excellent test files
for other file utilities.
FSInfo
This mode is one of the more interesting and immediately usable modes. It provides you with
statistics regarding the file system. For example, you can use it to obtain a list of active drives on the
current system. You could redirect this list to a text file for use with a script or output it to a batch
file to perform a task on every attached drive.
