How to run javac with paths as an argument that contains spaces?

I am trying to run the following

javac -Xlint:unchecked -classpath C:/Users/a b/workspace/ @C:/Users/a b/workspace/files_to_compile

but i get

javac: invalid flag C:/users/a

I also tried to surround both paths with double quotes, but it doesn't seem to help a bit:

javac -Xlint:unchecked -classpath "C:/Users/a b/workspace/" @"C:/Users/a b/workspace/files_to_compile"

What am I doing wrong? The same code worked correctly on other computers (probably because they did not have spaces in their paths ..).

Finally, I came to a solution to the problem, and, I think, no one here could have guessed this.

The key to the answer is that the contents of the file list (denoted by @ in the arguments) will usually contain each of its lines with the original substring equal to the one that passes both the class path and @file.

So..

EDIT:

Also, in your question, I noticed the use of slashes (/) in paths, do not all window versions use backslashes (\) as file delimiters? I saw your comment somewhere in this thread, stating exactly this, so I assume that you are sealed in the question.
