One approach I've seen for this is to do the scribbling (writing,
copying, changing of permissions, etc.) somewhere hidden on the same
file system and then when that's finished move the item to the
Finder-visible location.
In general, this is the best approach.
This also looks very easy: Since items with names beginning in the
dot "."
are hidden, simply prefix the item's name with a "." while you are
scribbling, and then when you're done scribbling, rename it,
removing the
"." prefix.
Should that do it, or am I oversimplifying?
The only arguments against this approach that I can think of at this
hour are:
- some filesystems (but not many, to be honest) can't deal with any
sort of lengthy filename starting with a dot.
- from a robustness perspective, having a single place where you
write temp files means that if your app crashes and restarts, you can
reap stray temporary items on a per-volume basis, rather than leaving
invisible turds lying all over the volume
- other systems (Windows) will see these files if the directory is
exported
None of these seem like showstoppers to me...
