[cvsnt] How to shrink big binary file?

If you want to keep the history around then none that I can think of. 
The disadvantage is that the history isn't contiguous (e.g. Tortoise 
won't see the full concatenated history for the file).

Yes.  Be sure to use the latest available, we've fixed some issues in 
the rename code working toward our new commercial release.  You might 
not be affected by those cases, and I don't think any caused anything 
serious as data loss at any rate.

Yes.  The RCS file will get a slightly different name automagically. 
Run a quick test and you'll see how it works:

C:\My_Documents\Test\stanley-test2\junk\ren_test>cvs add Bo.txt
cvsnt server: scheduling file `Bo.txt' for addition
cvsnt server: use 'cvsnt commit' to add this file permanently

C:\My_Documents\Test\stanley-test2\junk\ren_test>cvs ci -m ""
cvs commit: Examining .
RCS file: /test2/junk/ren_test/Bo.txt,v
done
Checking in Bo.txt;
/test2/junk/ren_test/Bo.txt,v  <--  Bo.txt
initial revision: 1.1
done

C:\My_Documents\Test\stanley-test2\junk\ren_test>cvs ren Bo.txt Bo.old.txt
cvs rename: Warning: rename is still experimental and may not behave as 
you would expect

C:\My_Documents\Test\stanley-test2\junk\ren_test>cvs ci -m ""
cvs commit: Examining .
cvsnt server: Examining .
/test2/junk/ren_test/.directory_history,v  <--  directory update

done

C:\My_Documents\Test\stanley-test2\junk\ren_test>echo New Hi > Bo.txt

C:\My_Documents\Test\stanley-test2\junk\ren_test>cvs add Bo.txt
cvsnt server: scheduling file `Bo.txt' for addition
cvsnt server: use 'cvsnt commit' to add this file permanently

C:\My_Documents\Test\stanley-test2\junk\ren_test>cvs ci -m ""
cvs commit: Examining .
RCS file: /test2/junk/ren_test/Bo.txt_1,v
done
Checking in Bo.txt;
/test2/junk/ren_test/Bo.txt_1,v  <--  Bo.txt
initial revision: 1.1
done

Note that "Bo.txt_1,v" is the new "Bo.txt" RCS file.  Also note that I'm 
using the latest commercial beta -- I think the recommendation with 2382 
is that you go to the parent directory and commit the directory with the 
renamed file in it.
