Replying to [comment:2 hellik]:
> AFAIK overwriting existing files (--overwrite) isn't really working in
the windows system architecture as opened files - in contrast to
linux/unix - can't be overwritten.
1. Overwriting open files and overwriting existing files aren't normally
the same thing.
2. There is no inherent problem with modifying open files (i.e. having
multiple processes open a file for writing). The problem comes from
deleting, renaming or replacing (renaming onto) open files. Unix allows
this, Windows doesn't.
The issue boils down to determining why files which were opened by one
command are still open when it comes to running a subsequent command.
It may be related to database drivers, as these may persist after the
command which started them has terminated (they shouldn't, but past
reports suggest that they sometimes do).
Or it may be related to "services" such as indexing, antivirus, version-
control shell extensions, etc. Perhaps the initial access results in a
notification to the service, which then decides to take a look at the file
as soon as it's closed.
