Spanning Multiple Discs



I want to free up some hdd space by transferring data files to DVDs (to take advantage of their extra capacity).

I want to be able to work with the files just as if they were on my hdd so don’t want to create an image such as with Acronis TrueImage which I think only allows me to restore the full image not individual files.

I could create several compilations ensuring that each one doesn’t exceed the capacity of the DVD but this would be a slow process as I have a number of files in several folders.

Was wondering if anyone could help me decide which software allows for an ordinary data compilation to be spread across multiple discs.
