To create file using fsutil

Fsutil can be used only by administrators. For non-admin users it throws up below error.

I'm guessing you're trying to create a text file?
我猜你想创建一个文本文件？
New-Item c:\scripts\new_file.txt -type file
Where "C:\scripts\new_file.txt" is the fully qualified path including the file name and extension.
其中“C:\scripts\new_file.txt”是包含文件名和扩展名的完全限定路径。

street smart (quick, dirty but works): (might change the file and add an invisible character which might cause the compiler to fail)
street smart（快速，肮脏但有效）：（可能会更改文件并添加一个可能导致编译器失败的不可见字符）
$null > file.txt
$null > file.html
Textbook method:
教材法：
New-Item -path <path to the destination file> -type file
example:
例子：
New-Item -path "c:\" -type file -name "somefile.txt"
OR
或者
ni file.xt -type file
absence of -path parameter means it creates it in the current working directory
缺少 -path 参数意味着它会在当前工作目录中创建它

Here is another way to create a blank text file in Powershell which allows you to specify the encoding.
这是在 Powershell 中创建空白文本文件的另一种方法，它允许您指定编码。
First example
第一个例子
For a blank text file:
对于空白文本文件：
Out-File C:\filename.txt -encoding ascii
Without -encoding ascii, Powershell defaults to Unicode. You must specify asciiif you want it to be readable or editable by another source.
如果没有-encoding ascii，Powershell 默认为 Unicode。您必须指定ascii是否希望它可以被其他来源读取或编辑。
Overwriting the file with new text:
用新文本覆盖文件：
"Some Text on first line" | Out-File C:\filename1.txt -encoding ascii
This replaces whatever text is in filename.txtwith Some Text on first line.
这将替换任何文本是filename.txt与Some Text on first line.
Appending text to the current file contents:
将文本附加到当前文件内容：
"Some More Text after the old text" | Out-File C:\filename1.txt -encoding ascii -Append
Specifying -Appendleaves the current contents of filename.txtalone and adds Some More Text after the old textto the end of the file, leaving the current content intact.
指定-Append叶子的当前内容filename.txt单独并添加Some More Text after the old text到文件末尾，离开当前的内容不变。

# encodings:
New-Item file.js -ItemType File -Value "some content" # UTF-8
"some content" | Out-File main.js -Encoding utf8 # UTF-8-BOM
echo "some content" > file.js # UCS-2 LE BOM
