Hi,
As you have mentioned .... you have read only access ... you can read it but you can't delete it.
It depend on which operating system you are ....
on unix systems you can use "chmod +w <file_name> " this will again depend if you have permissions.
on windows you can right click and check for properties ... there is check box <read only> you can deselect it.
Hope this will work
