How to get files files which were last used

Hi,

is it possible to determine the files which were last used from
different applications (e.g. "readme.txt was used in the last 2 hours")
on MAC with Java by default System calls?

Or is this only possible by writing a sort of "trigger" application?

Thanks,

Peter Vermeer

All java.io.File objects have a lastModified method that returns a long
with the last time that the file was last modified.

There is talk of adding a Most Recently Used document feature to JDIC
(and thence to Java SE), but nothing solid yet.

Quite possibly someone else has come up with a Mac specific solution.

On windows, there is a Last Access date which tell the last time
anyone read/wrote the file. Checking if it exists or checking its
date does not count as an access. You can get at it with

You would have to implement the native method for MacOS.

I don't know if Macs maintain a last access time. It is an expensive
thing to maintain.

So FileTimes gives me a list of last modified or new files independent
of the application the files came from?
For example in MS Word I change an existing file. Now I start FileTimes
which gives me back the filename?
