Right, many thanks to those who have offered advice. I'm conscious that as I've drifted from a coding topic then I'm probably in the wrong mailing list, but everyone has been very patient up to now and I'm hoping that a fix is in sight! :) I have done a backup of the Dats.fs file (took three days!). I have used fsdump and fstest to produce listings about my Data.fs file - fsdump produced a 2.67GB textfile! I have tracked down the first entry that I believe begins all the deletes: tid=0367c03fc4325022 time=2006-08-26 08:31:45.983563 offset=749481328632 user= admin description=/library/reference/manage_delObjects If I'm right ... does that mean if I trim the Data.fs file to 749481328632 bytes long and start Zope off again, that the files should be restored? If so, does anyone know of a good way of trimming such a large binary file down to a specific size? I'm using Suse Linux as a server. Cheers, and thanks again, Kris. www.danceswithferrets.org
