Dear Henrik,

My guess would be that we will know in advance where 
all the files will be located and can just ask through normal
system calls the size of all the files.  Something like the
statfs. 

Only since I was looking into the OSE class library in detail
they have a File System class that lets you get this information.
The advantage might be that it works on both win32 and unix.

I'm sure there are others like this.

Regards,
- Mark

Dear Challenged,

For a couple of reasons the Storage Manager should know the size of the
files (i.e., the Objectivity databases). 
Do you know an easy way of getting them? 
Are they stored in the Tag DB?
Can you get them through an Objectivity interface (even when they are on
HPSS)?
Any other ways?

Thanks, - Henrik
