Another way to get the date format with – as separator is to open the regional settings in the control panel & select customize. Then go to the tab named date. Here, change the date separator from “/” to “-” and OK.

You can check the format by going to the cmd prompt. Type echo %date% and press enter

example
c:\>echo %date%
c:\>2010-09-22

I also had problems with the output not correctly formed, but I’ve solved modifying the numbers in the string:

my system when I type DATE command shows the date in the format DD/MM/YYYY

so, i’ve modified the string with the format %DATE:~-4%-%DATE:~3,2%-%DATE:~0,2%

try to look what format is using your system {type DATE without parameters) and then adjust the numbers in the string {they are the positions of the char to show)…

I have a problem when using the date stamp command as indicated above.
Using Ryan’s original example in the main article where hew says:
”
%DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_cybernet.7z

which for today would give a result of:

2008-01-03_cybernet.7z
”

I get the following output: (Considering the date is 2010-08-05)
7Zip creates a the following with the date elements making up separate folders…
08/05-/0-/0_cybernet.7z

I am using the date stamp code exactly as in the example.

What am I doing wrong?!?

I would archive the files depending on the creation date. Is there a possibility? I didn’t find something about this in the help or in the community. Thanks in advance!

Can you specify an output directory using a UNC path?

You can use a batch file to delete the files. Just use the “del” command.
