Virtual PC 2004 SP1
1. Select a range, then Copy/Copy/TS to a Shared folder (+=- network drive).
2. Select a shorter range, then Copy/Copy/TS to the same file.
2r. Asks to overwrite, then saves as expected.
But file size is not reduced: existing extra data are left as is.
Ftr, overwriting to a local drive works fine.
This could be an issue related to Virtual PC, (though I don't think so after some basic tests).
Does anyone reproduce (or not) with a similar setup?
