Copying an open file dangerous?
Posted on 2000-02-25
I have an AppleScript that executes nightly and does a Finder copy my Microsoft Outlook data files to another computer to back up my email.
Outlook checks for mail every 10 minutes (as I have it set up). So, it is possible that the contents of the data file may change while the Finder copy is going on.
Does that mean that the copies file may end up in an inconsistent state? Or does the file system make sure that when the Finder is copying a file, updates will be ignored by the process doing the copy, i.e. the file looks as it did at the beginning of the copy operation?
