2003在安装的时候选择了fat32文件格式，安装后还能改么？

[zcwok]

不用再重装系统吧。太麻烦了。

[icuc88]

可以，使用命令。

convert c: /fs:ntfs

[ravenkatte]

对，convert x:/fs:ntfs

[zcwok]

看到一个贴子说必须先用fsutil file createnew 命令创建占位符文件，这有什么用处呢？另外这样转换成ntfs的性能，和直接格式化成ntfs的性能有差别么？

[cxyPioneer]

在系统范围内好像不行，要借助第三方软件

一般来说，在使用convert命令的/cvtarea参数时，才会使用fsutil file createnew。以下是转载：

/cvtarea参数指定将主控文件表 (MFT) 以及其他 NTFS 元数据文件写入相邻的现存占位符文件中。该文件必须位于要转换的文件系统的根目录下。在运行 convert 之前，首先必须使用 fsutil file createnew 命令创建占位符文件。Convert 并不创建此文件。Convert 使用 NTFS 元数据覆盖此文件。完成转换后，会释放此文件中所有未被使用的空间。


如果你真要研究这个问题，就应该先对MFT有所了解

下面是帮助里面关于convert 和fsutil的信息：
/cvtarea:FileName
For advanced users only. Specifies that the Master File Table (MFT) and other NTFS metadata files are written to an existing, contiguous placeholder file. This file must be in the root directory of the file system to be converted. Use of the /CVTAREA parameter can result in a less fragmented file system after conversion. For best results, the size of this file should be 1 KB multiplied by the number of files and directories in the file system, however, the convert utility accepts files of any size.
For more information about using the /cvtarea parameter, see "File Systems" at the Microsoft Windows XP Resource Kits Web site.(http://www.microsoft.com/)

Important

You must create the placeholder file using the fsutil file createnew command prior to running convert. Convert does not create this file for you. Convert overwrites this file with NTFS metadata. After conversion, any unused space in this file is freed. For more information about the fsutil file command, see Related Topics


结论：

fsutil file createnew对于普通用户来说，是没有必要的。也不需要。当你要用到convert里面的/cvtarea:FileName 参数的时候才可以考虑。
