I think I am looking for the ESC char to use in a DOS Batch file

Question

The code that is confusing me:

set CLEAN=\Users\%USERNAME%\Documents\Directory One\Sub Directory\30% Dalton.txt
IF EXIST %CLEAN% echo "It Works"

This code will never work because the file name has a " % " char

Is there a way to get around this and produce the Echo "It Works"

Answer 1

set CLEAN=\Users\%USERNAME%\Documents\Directory One\Sub Directory\30%% Dalton.txt
IF EXIST "%CLEAN%" echo "It Works"

Answer 2

Use a double % sign. A quick Google led me to the answer.
