Use:

/*
Creates an empty file, which can take all of the disk
space. Just specify the desired file size on the
command line.
*/

#include <windows.h>
#include <stdlib.h>

int main (int argc, char* ARGV[])
{
    int size;
    size = atoi(ARGV[1]);
    const char* full = "fulldisk.dsk";
    HANDLE hf = CreateFile(full,
                           GENERIC_WRITE,
                           0,
                           0,
                           CREATE_ALWAYS,
                           0,
                           0);
    SetFilePointer(hf, size, 0, FILE_BEGIN);
    SetEndOfFile(hf);
    CloseHandle(hf);
    return 0;
}

创建任意大小的虚拟文件，其中填充了空格或填充了不可压缩的内容(由您选择)。这是一张截图:

临时文件应该存储在Windows临时文件夹中。根据Rod的回答，您可以使用下面的一行代码创建一个5 GB的临时文件，该文件返回文件名

[System.IO.Path]::GetTempFileName() | % { [System.IO.File]::Create($_).SetLength(5gb).Close;$_ } | ? { $_ }

解释:

[System.IO.Path]::GetTempFileName() generates a random filename with random extension in the Windows Temp Folder The Pipeline is used to pass the name to [System.IO.File]::Create($_) which creates the file The file name is set to the newly created file with .SetLength(5gb). I was a bit surprised to discover, that PowerShell supports Byte Conversion, which is really helpful. The file handle needs to be closed with .close to allow other applications to access it With ;$_ the filename is returned and with | ? { $_ } it is ensured that only the filename is returned and not the empty string returned by [System.IO.File]::Create($_)

可以使用cat powershell命令。

首先创建一个包含几个字符的简单文本文件。输入的初始字符越多，它变大的速度就越快。调用out。txt。然后在Powershell中:

cat out.txt >> out.txt

等待足够长的时间，使文件足够大。然后按ctrl-c结束它。

检查Windows Server 2003资源工具包工具。有一个名为Creatfil的实用程序。

 CREATFIL.EXE
 -? : This message
 -FileName -- name of the new file
 -FileSize -- size of file in KBytes, default is 1024 KBytes

它类似于Solaris上的mkfile。

除了编写一个完整的应用程序，我们Python人可以用四行实现任何大小的文件，在Windows和Linux上使用相同的代码片段(os.stat()行只是一个检查):

>>> f = open('myfile.txt','w')
>>> f.seek(1024-1) # an example, pick any size
>>> f.write('\x00')
>>> f.close()
>>> os.stat('myfile.txt').st_size
1024L
>>>
