What I already have: %date% is the windows variable that stores the current date. When I use echo %date% the value Tue 07/25/2017 is correctly printed.
But when I try to do mkdir %date% the created folder is Tue 07 because windows does not recognize / as a valid character.
How do I get around this?
You can not add / to the folder name.
You should use a date mask ...
Usually YYYYMMDD or ANO MES e DIA is used, so it's easy to sort the files by date ...
Here is an example of how to implement ...
set filedatetime=%date% // ou qualquer outra data
set filedatetime=%filedatetime:~6,4%%filedatetime:~3,2%%filedatetime:~0,2%
echo "%filedatetime%" //exemplo da saida... "20170725"
Then you just have to give
mkdir %filedatetime%
Since the requirement is only to show the whole date, try:
mkdir %date:/=%
Change the bars by hyphens by adding :/=- after date
mkdir %date:/=-%
