No Copy

Is there any way to stop a file from being copied? I'd like to be able
to move a file but not copy it.
Thanks

In what context???

In a VBA procedure, you can probably can do that by using
the Name statement.

Windows group.

Hi Marsh & DS

There are no permissions in NTFS or FAT file systems that would prevent
a file from being copied if it can be read - and it's extremely hard to
imagine how that could be achieved (short of mandating special hardware
and software as in the various DRM systems now being fought over).

Thats disappointing! It sounds like a simple thing to ask for.

It is a simple thing to ask for, but it wouldn't be a simple thing to
implement in a standard Windows computer. Preventing the file from being
copied would mean somehow "labelling" every bit of data read from it and
ensuring that "labelled" data couldn't be written to disk - while
allowing it to be moved would mean allowing each "labelled" bit to be
written to disk only when its counterpart in the original file had been
deleted.

Even if a system like that could be implemented - which I doubt - if the
contents of the file can be displayed on screen or printed they can be
captured by other software.
