How do I change file permissions on Windows?

How can I programmatically change a file's permission to be writable?

The input are read-only files, and I want to know if there is a general a way to guarantee that I can turn on writability/turn off read-only, no matter what version of Windows (XP, server-2003, or higher).

Here's another way. Install cygwin on your windows system Then access your folder using

cd /cygdrive/c/

Then use chmod for changing permissions.

FileUtils.chmod 'a+x', %w(foo.txt bar.txt)

That is based off of @Arup's comment of using http://ruby-doc.org/stdlib-2.0.0/libdoc/fileutils/rdoc/FileUtils.html#method-c-chmod -- which works for me, and it stays in pure ruby.

The read-only attibute in Windows is set with the attrib command.

exec "attrib +R 12345.jpg" #sets the read-only file attribute
exec "attrib -R 12345.jpg" #removes the read-only file attribute
