Two questions on multisession recorded disks

[perfection]

I have burned 100 CDs containing my product brochure 2010 in multisession mode i.e. the CDs are open for further writing. The reason is that i may or may not require to distribute this last lot of 100 CD brochures this year. The data space used is only 200 MB. My thinking is that if not used this year i can ide the present 2010 data and burn another 200 Mb of 2100 data (i.e. my next years catalogue data).

My questions are:
01. If i need to distribute the multisesion CDs of 2010 the way thy are right now (multisession open) would they be playable (autorun and all) on my potential customer's PC or do i have to compulsorily finalize them?

02. If i need to finalize the Cds necessarily, which software can do this . I use power2Go to urn the CDs. However I cannot find how to finalize them. What i have to do is add a harmless file (such as a blank text file) as additional data and then the burn now button appears ready for use. Is there a way to finalize without the addiional data being pretentiously added? Is there software that only finalizes? Lastly, can my discs be fialized on another buner and another program?

I think a mod would care to have a word with you for bumping your post in this way.

Now, to answer, IIRC the act of putting any more data on to a CD closes the previous session which normally makes the old data inaccessable. You can use some tools to access the old data but your typicial user will not be able to do this.
