Hammer: recovering a directory

[elekktretterr at exemail.com.au]

Hi all,

How does one recover a directory. ie. a database directory that has many
files at a specific time?. How can I guesstimate the right transaction ID
created approximately 5 minutes( or 5 hours ago) so that I may recover the
directory? Is there any tool to display all transaction ids on the file
system between specific times?

Thanks,
Petr
