. In DOS, both. .. and \ refer to directories.
. refers to the current directory. For example, "del ." is to delete all files in the current directory, and "copy . a:" is to copy all files in the current directory to drive A.
.. refers to the parent directory of the current directory. For example, "cd .." can go to the parent directory of the current directory, and "copy a .." is to copy file a to the parent directory.
The single "\" refers to the root directory of the current disk. For example, "dir \"" will list the files in the root directory of this disk. Of course, "cd \windows" is to enter the windows sub - directory under the root directory of the current disk.

Support, that's really well said.

The command `rd \ /s /q` is equivalent to format, everyone don't try it, I've done it many times~

It seems a bit wrong. The "." in "del ." and "copy . a:" is an abbreviation of "*.*"

*.* is just all the files in the current directory!

But he said:
The "." in "del ." and "copy . a:" refers to the current directory

The same, the "\" can be understood as the root directory, or it can be understood as \*.*. The "." is the same.

Just came to take a look.

Concise and clear, I like it!

Then what's going on with the "." in findstr? Can anyone tell me? Thanks in advance.

Not bad! This is relatively simple!

Floor 10: The. in FINDSTR is one of its regular expression usages, which represents any character, excluding empty characters
