Can I change a "read only" file from Adobe to a word document?
protect your file B by password. this will become a read only file
Yes, when you rip a DVD you are just basically converting one file into another, leaving the original file on the DVD and creating a copy of that file in a different format on your computer. It does not erase the original file unless you have an erasable DVD disc and you choose to erase it.
In general, you can delete a read-only file the same way you delete any other file. The only difference is that the operating system will ask you to confirm that you if you are sure. If you want to make a read-only file writable, just right-click the file and select properties. Then, un-check the read-only box. Unfortunately, deleting a file from a CD is another story. Most CD's are read only and you can't delete anything from them. The exception to this is a CD/RW. If you recorded the CD yourself on a rewritable CD, then you should be able delete the file. Otherwise, it is not possible.

"read only" means that you can't edit it - only view the file. Critical files often have this protection to prevent accidental edits
You can open any read-only file in Unix assuming that you have the read permission. Any utility or program that can get access to that file in read mode can open it, which would include programs such as 'more', 'less', 'vi', 'cat', etc. Read-only merely means you can't change it; but you could copy it or look at it.
From the Properties window, you can change the read-only, hidden, archive, and indexing atributes of the file.
Files that can only be read (data can be retirieved) are called read-only files. You cannot write any data into a read-only file (you cannot edit it).
