If you’re talking about a floppy disk, check to make sure the little tab on the corner isn’t closed. This is a read/write protector. When you can see through the little hole, then the disk is read-only.
If you’re talking about a CD, CDs cannot be written to and so you should copy the code to your hard disk, then work on it.
i saved the cd rom files to my harddrive and it still comes up with the same message, the files on the disk used to work, but then they started saying read only
If your saving files onto a folder, you may want to check and see if you have the ability to change files saved within the folder. You may be trying to acheive the impossible. :ahh:
If that’s the case, try saving the file onto the desktop and then opening it. You should be able to work with your program that way.
Also check to see if your easyC/mpLab license hasn’t expired. That could also be causing a problem. Other than that, I don’t know what else to say.
If you are trying to use a school computer, you may be locked out of certain directories for security reasons, and hence, you aren’t able to make changes or save anything onto that directory.
Try creating a folder on the desktop, or some other directory where you have permissions to write to and save your work.
