how to recover space after delete files ?

[fafilberg]

Hi, I renew the stored data on CD constantly so I have to delete files and dirs, multisessions doesnt free space.
How can I recover free space using Nero, I know that I can use InCd or another program like this that use UDF, but I red a few days ago that packet writing is not reliable, in fact I red it when I had a problem with it.
I think InCd is the better way to store data, becouse you can copy/move directly from browser, but if it is not reliable it is useless, so what kind of solution can I apply to this ?.


Thanks.
