Hi
i want to create a file which cluster continued and can not move. this file’s attribute likes pagefile.sys. which way can help to create this file?
Thanks in advance!
IIRC you cannot move a file that is open, so that makes that easy. I don’t
know what you mean by cluster continued, if you mean cluster contiguous
pagefiles are definitely not so.

Perhaps you can use a dedicated partition? What exactly do you want to do?

… using a dedicated partition alone will not help to create a file with
contiguous clusters.

Alone not, but the idea was to have a separate partition you access RAW.
The separate partition is to avoid influence from user usage on the regular
partitions and avoid problems with your direct access on user usage.
If you want to play you could even write your own dumbed-down file system
that would do all the work for you.

To Edouard:
thanks for you answer! Do you advice me that i allocate some space form the disk,and use this space create a partition,then use the partiton as a file?
But i want to create a file on the partition which has existed on the disk.beacuse i want to use this file as a disk.
thanks!
Several individuals here do consulting and will be happy to design your
system. They will even develop it for you.
If you want to do it yourself, read the specs on the FAT file system. Study
the sources for FASTFAT.sys. Look at the WDK’s documentation for the
storage stack. Many people have done this and there are many samples
available, though mostly in executable form only.

i know that on the FAT FS,i can modify the FAT table to get the contingous clusters’ file.but i want to create the file on the NTFS!
thanks
If I understand correctly, you want to create a virtual volume from a file
that sits on another volume?
For this, it is not required to have the file contiguous.

To Edouard:
Yes.i want to create a virtual volume.to create a file contiguous is only for Read/Write operation easily.can you give me some advice to create a contiguous file?
thanks!

You will do the read write through the file system, not directly from the
storage device. Thus you don’t need to bother how/where is your file.

I would agree that you do not need to do so, and as a design it is quite
limited. However, if you wish to do this, the easiest way that I know
of is to create a file and then defragment it using the documented FSTCL
codes. See the SDK documentation for defragmentation if you are
interested in this.
Good luck,
mm

thanks for you answers.you give me a new way to get the contigous file!i will try it !thank you!
If the file was opened with FILE_SHARE_DELETE, you can rename (move) it.
This is the reason why you can rename away a .dll or .exe that is in use -
because LDR opens the files with FILE_SHARE_DELETE.

Hmm. Just now noticed that you were talking about cluster moving and not
file name moving. Disregard my comment.
