\b0 is 1.0 trash. If you use two computers (one which is 1.0 based and another which is 2.0 based) remember to empty the trash on both machines. If you use 2.0 exclusively, you may wish to delete the 1.0 trash directory.\
\
Alternatively, rather than emptying the trash under 1.0
\i and
\i0 2.0, you may wish to symlink the two directories. When all of your machines have been upgraded to 2.0, you can then remove the symlink.\
