FileMaker Pro 2.0 warning
#316

I spoke with Claris Tech Support yesterday about a problem I was having with
several FileMaker Pro databases after receiving the 2.0 upgrade.  Turns out
there's a potential big-time problem when converting files unless you do the
right things first.

The problem involves any FileMaker Pro file that was created or used under 
1.0v1.  Seems 1.0v1 had a problem with its indexes, and doing a RECOVER
under 1.0v2 or 1.0v3 would fix it.  If the problem remains, however, and
you simply convert the file to 2.0 format, you'll lose data, and according
the person I spoke to at Claris there is NO way to recover it.

The key to avoiding this is to RECOVER the file first - don't just open &
convert it with FM Pro 2.0.  I don't know whether doing a recover of a 1.0vx 
file in 2.0 also converts it, since I had already converted the files by the
time I learned this.

There's supposed to be an insert in the package that explains this, but mine
must have been one of the first shipped, because it didn't have one.  

Be warned - this cost me a lot of grief, since I didn't understand what had
happened and then put in many hours adding data to one of my most important
files & couldn't simply go back to the pre-2.0 backup.  It's amazing that they
didn't discover this during development and test of 2.0 - it's also a little
bothersome that a corrupted index can permanently damage a FileMaker file with
no way to recover the data (it's still there - you just can't get at it), but
according to Claris tech support, that's the way it is.

I know this doesn't make up for the bug you've mentioned, but such problems
in general (eg. you update the wrong version of a database file) can be
avoided by time-stamping (creation/modification date) on records automatically,
allowing all records created/modified during a given period to be separated out
and exported to the correct version of a file.

There's no reason why such a timestamp shouldn't be added to records (or
for that matter, be made part of any record automatically -- anyone at
Claris listening ? :)  ).

Just a thought.

FileMaker Pro has this ability; however you have to impliment it by setting
up a field for it.  Not everyone wants to do this, so it is optional.
