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 | ? { $_ } it is ensured that only the filename is returned and not the empty string returned by [System.IO.File]::Create($_)

快速执行还是在键盘上快速输入?如果你在Windows上使用Python，你可以尝试这样做:

cmd /k py -3 -c "with open(r'C:\Users\LRiffel\BigFile.bin', 'wb') as file: file.truncate(5 * 1 << 30)"

打开Windows任务管理器，右键单击正在运行的最大进程，然后单击“创建转储文件”。

这将在临时文件夹中创建一个相对于内存中进程大小的文件。

您可以轻松地创建一个千兆字节大小的文件。

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;
}

fsutil file createnew <filename> <length>

其中<length>为字节单位。

例如，要创建一个名为'test'的1MB (Windows MB或MiB)文件，可以使用这段代码。

fsutil file createnew test 1048576

但是Fsutil需要管理权限。
