windows command to get size of files in folder

It can take a while for Windows 10 to calculate the data size of the files in a single directory. You can use the following script in command prompt to get the total size more quickly:


powershell -noprofile -command "ls -r|measure -sum Length"

The command gives us the file count and the number of bytes, which is 409 MB. Powershell can be activated from command prompt.
