'Chain1.cdf' has been modified message on Quartus II 13

Hi,

I'm using Quartus II 13.0.1 64-bit and sometimes (I don't know when) I get a "'Chain1.cdf' has been modified. Do you want to save your changes?" message.

I'd like to know what a .cdf file is and if this message is important.

Thank you.

    The message comes from the Programmer GUI. I typically ignore it.

    Cheers,

    Dave

    Like the previous post mentioned, it is for the programmer. If you notice , some fpgas can have other cpld's in the design. When you auto detect , it will show the current chain set up such as stratix v with max v chips and even flash chips... It is usually different from the default settings. If you save the updated chain. It shouldn't keep asking you to save it. Hope it didn't complicated things :)
