Dear Friends,
I found some useful utilities available with windows XP & 2003. Normally in Linux we use to create empty file with bigger size for some testing and administratve purpose using a command " touchfile ". Similarly in windows also there is command line for that , which is mentioned below Command name File name Size in Bytes fsutil file createnew SystemFileDoNotDelete.dat 53687091200 Reference: http://www.ss64.com/ , I have attached the possible command lines with this utility.

FSUTIL.exe (Win XP/2003 server)
File and Volume specific commands, Hardlink management, Quota management, USN,
Sparse file, Object ID and Reparse point management
Create a hardlink
FSUTIL hardlink create <new filename> <existing filename>
Eg : fsutil hardlink create c:\foo.txt c:\bar.txt
Create a new file of a specific size
FSUTIL file createnew <filename>
Eg : fsutil file createnew C:\testfile.txt 1000
Set the short name for a file
FSUTIL file setshortname <filename> <shortname>
Eg : fsutil file setshortname C:\testfile.txt testfile
Set the valid data length for a file
FSUTIL file setvaliddata <filename> <datalength>
Eg : fsutil file setvaliddata C:\testfile.txt 4096
Set the zero data for a file
FSUTIL file setzerodata offset=<val> length=<val> <filename>
offset : File offset, the start of the range to set to zeroes
length : Byte length of the zeroed range
Eg : fsutil file setzerodata offset=100 length=150 C:\Temp\sample.txt
List all drives (including mapped and Subst drives)
FSUTIL fsinfo drives
Query drive type for a drive
FSUTIL fsinfo drivetype <volume pathname>
Eg : fsutil fsinfo drivetype C:
ListLocalDrives.cmd - List all drives on the local computer
Query volume information
FSUTIL fsinfo volumeinfo <volume pathname>
Eg : fsutil fsinfo volumeinfo C:\
Query NTFS specific volume information
FSUTIL fsinfo ntfsinfo <volume pathname>
Eg : fsutil fsinfo ntfsinfo C:
Query file system statistics
FSUTIL fsinfo statistics <volume pathname>
Eg : fsutil fsinfo statistics C:
QUOTA Management
FSUTIL quota {query|disable|track|enforce } C:
FSUTIL quota violations
FSUTIL quota modify <volume pathname> <threshold> <limit> <user>
Eg : fsutil quota modify c: 3000 5000 domain\user
Find a file by user name (if Disk Quotas are enabled)
FSUTIL file findbysid <user> <directory>
Eg : fsutil file findbysid scottb C:\users
File system options:
FSUTIL behavior query option
FSUTIL behavior set option
FSUTIL dirty query <volume pathname>
FSUTIL dirty set <volume pathname>
Where option is one of:
disable8dot3
allowextchar
disablelastaccess
quotanotify
mftzone
Eg : FSUTIL behavior query disable8dot3 1
FSUTIL dirty query C:
Query a reparse point
FSUTIL reparsepoint query <filename>
Eg : fsutil reparsepoint query C:\Server
Delete a reparse point
FSUTIL reparsepoint delete <filename>
Eg : fsutil reparsepoint delete C:\Server
Edit an object identifier
FSUTIL objectid {query | set | delete | create}
Set sparse file properties
FSUTIL sparse queryflag <filename>
FSUTIL sparse setflag <filename>
FSUTIL sparse queryrange <filename>
FSUTIL sparse setrange <filename>
Eg : fsutil sparse queryflag "C:\My Test.txt"
Query the allocated ranges for a file
FSUTIL file queryallocranges offset=<val> length=<val> <filename>
offset : File Offset, the start of the range to query
length : Size, in bytes, of the range
Eg : fsutil file queryallocranges offset=1024 length=64 C:\Temp\sample.txt
To run FSUTIL, you must be logged on as an administrator or a member of the
Administrators group.
Sparse files provide a method of saving disk space for files that contain
meaningful data as well as large sections of data composed of zeros. If an NTFS
file is marked as sparse, then disk clusters are allocated only for the data
explicitly specified by the application.
e.g. The Indexing Service, stores it's catalogs as sparse files.
With 8.3 filennames disabled you'll notice a performance improvement only with
a large number of files (over 300,000) in relatively few folders where a lot of
the filenames start with similar names. Not having 8.3 filenames available will
prevent the use of old applications such as Word 2.0 and Excel 4.0
FSUTIL behavior query disable8dot3 1
If you have a lot of small files, you may need a larger Master File Table to
avoid MFT fragmentation:
FSUTIL behavior set mftzone 2 will reserve 25 % of the volume for the MFT.
1 = 12.5 %(default),
2 = 25%
3 = 37.5%,
4 = 50%
The last access time attribute of NTFS can slow performance, if you disable it,
the time set will simply be the Creation Time.
FSUTIL behavior set disablelastaccess 1
Some features in fsutil are reported to not work correctly under FAT or FAT32
volumes e.g. FSUTIL dirty query.
