I have a shared hard drive on my computer that is on a windows
network. On that hard drive a have folders with the history of
previous work we have done over the last 10 years. Is it possible so
those folders and contant of the folders to be setup so there has to
be a pass word type in before they can be deleted or changed...
Well, sort of, but not natively with XP; it'd require a 3rd party app if
it has to also protect YOU from deleting them. It's easy enough to
preven others, but you would still be able to.
You don't say what programs you use to open them, but some allow you an
option to open files as "read only" but not on a blanket/permanent
basis AFAIK.
There are 3rd party programs which would do that for you, but I don't
have any to recommend. I try to stay away from 3rd parties as much as I
can, especially with important data. Ymmv
Someone could write a script for you that would always open them in read
only mode IF your program had that ability and you could get the script.
This isn't the newsgroup for that though.
IMO it would be a LOT better to:
-- Make a backup of ALL of those files.
-- Besides that backup, also copy them to DVDs. CLOSE the DVDs so they
can never be written to again; then at least those files can never be
changed and they become a sort of backup bible. At least two copies of
backups are needed, 3 being the most reliable with the 3rd copy kept
offsite, in a different building (fire, theft, etc).
-- Get yourself a CRC or HASH calculator and run it on all the files.
Make the CRC/HASH numbers part of the backup and DVDs. Then if you
suspected a change had occurred in any program, you would rather quickly
(not instantly) tell, and you'd know to refresh it from backup.
-- Of course, newly created files, if that's a consideration, would need
to be built and backed up accordingly too.
There are more ways yet, but they would all depend on even more 3rd
party stuff, so I guess the decision/research would be up to you.
