For ease-of-use setup an alias. For example:
alias prime-cache="C:/primecache-content.sh"
Then in the future, when you want to preload data, you'll be able to read from the current folder like so:
prime-cache .
# or
prime-cache "D:\Games"
# or
prime-cache "D:\Game1Folder" "D:\Game2Folder"
# or from list
prime-cache ./preload-list.txt
