What is the sequence for changing the CHMOD settings of files using the FileManager in WFSections 2.1?

Normal CHMOD codes are like this:

777 = read/write/execute access to everyone
666 = read/write access to everyone
444 = read only access to everyone

but WFSections uses a four number system and I can't set the files to the equivalent settings.

What CHMOD settings in WFSections would give me the above settings? e.g. what settings in WFSections would allow me to set a file as 444 or read only?

There is a WF-Section 2.1 . Latest version I knew of was Wf-Section 2 beta 3? You could try 644, although you might need 666 on any upload directories.

According to the Zip file it's WFSection 2.1.

Anyhow, the problem is that WFSections doesn't use the 3 number CHMOD but a 4 number one and so doing 444 sets the file as something like 1537.

I've tried 0444 as well but to no avail.
