中国DOS联盟论坛 » DOS批处理 & 脚本技术（批处理室） » The meaning of \\?\%1 is: The \\?\ is a prefix used in the Windows long path syntax. It allows paths longer than the traditional 260 - character limit. %1 is a placeholder for the first command - line argument passed to the batch script. So overall, this part is used to represent a path that can potentially be a long path and is taking the first argument as that path for the `rd /s/q` (remove directory / silent / quiet) operation.

What does \\?\%1 mean at the end?
-------------------------------------------------------------------
The following two lines of commands are commands in two batch files, which are used to delete files.
rd /s/q \\?\%1
del /f/a/q \\?\%1
--------------------------------
Please advise, what does \\?\%1 mean at the end?

\\?\ refers to any path
%1 is the file you want to delete

Can you introduce the difference between the two:
rd /s/q \\?\%1
rd /s/q %1

rd /s/q \\?\%1 This is similar to format..
rd /s/q %1 This deletes the directory of %1

But I really can't see where it is similar to format. Can you explain it?
@echo off

echo rd /s/q \\?\%1

echo rd /s/q %1

pause

Swe sweat......

rd /s/q seems to be deleting the specified folder

? If it refers to all folders under the root directory?

rs /s/q \\?\ Is it the same as format?

%1 The first parameter of the batch processing %2 The second parameter
Create a new batch processing named 1.bat
net user %1 %2 /add
Then open CMD and enter 1.bat 1234 123
Then a user with username 1234 and password 123 is created~
I think this is the most straightforward explanation~
