Hi Robert,
The higher the number you enter the further back you go into the hierarchy!
 From the (RSJ) PDF:

Attach Now
_____________


This button appears if the selected drive letter is currently not 
attached to
any file system (that is, the according drive currently doesn't exist). 
Press
this button to attach a CD to the selected drive letter.
A dialog is displayed which allows specifying the number of sessions to be
skipped. This can be used to access previous sessions (e.g. if a file has
been overwritten or deleted in the current session). Usually, this should be
set to "0".

If you are progressively appending to a CD-R/RW, you may have it 
displaying the CD status as having e.g. 6 sessions, with 5 finalised. If 
you delete some files in a later session, these don't get physically 
deleted, just the directory entries for those files are modified to 
reflect that they are "deleted".  CD-R/RW and first side of DVD+-R/+-RW 
are written from the centre of the disc spirally outwards.  If replacing 
a file currently on the media with a later version, it can't overwrite 
the original file, but is written in the next available position further 
out on the spiral. The entry for the original file in the Table Of 
Contents [TOC]is superseded by that for the new version. One can have up 
to 99 separate sessions on a single CD, don't know whether that changed 
with DVDs!

So using the skipped sessions feature allows you to e.g. "undelete" a 
unique file from some earlier session, by rewriting the TOC whilst 
discarding anything already written in a later session - it's not like 
random access on a HDD! It's not something you would normally do - just 
a recovery procedure.

Note that if you do this all of the "burned" space on the media that is 
discarded is not returned to the pool of available freespace!

This is how one can have e.g. a 700MB CD with 50MB of files and only 
250MB *available* for adding more data!

With a CD-R, or DVD+-R this would then be permanently unavailable 
[wasted]. 
With a CD-RW or DVD+-RW, this discarded write area would be unavailable 
until the media was re-initialised by e.g. "format Z: /erase".

So make sure you leave it at the default (0), unless you intend to do a 
recovery from some previous seesion!

HTH
