Any advice when to use FileExists?

Just for completeness sake it should be noted, that FileExists will raise an exception, if the current user has insufficient rights to read the file.

in the very next second it could have the rights and vice versa

In what version of Delphi is this? Are you sure that it raises an exception? If it does then that is a change of behaviour from the XE days.

I don't have an up-to-date version to verify this with, but I seriously doubt what you claim is true.  Up to at least XE8, FileExists() was never coded to raise any exceptions.  I can't imagine Embarcadero would ever add exception handling to FileExists() in the years since that release.

Just happened to me in at least 10.4.2 may even be so in 11.2. But maybe it is something else, will try to put together a small demo, time permitting.

So, I have no Idea, what the issue really is, it is not FileExists. At least the way I try to reproduce missing privileges no exception is raised... so I retract that statement as bogus. Sorry for the fuss.
