I am running SDT and Visual Extend. When I add new fields, etc. and run my app (thru runtime - like a client), the updates get applied correctly but certain files are written like new in the update directory. If I dont catch it they overwrite my good files and I lose all the data. Not all files are re-created, it appears that only 41 do, and most of these (but not all are free tables). One of the files is a system counter file, VFXSYSID and that causes BIG problems. I cant figure out why it builds these tables in update since they already exist in the data directory and their structure hasnt even changed but I need a way to unilaterally stop this from happening. I know update can run as update all or a specific table, but is there a way to run it to ignore certain tables. I'm willing to hard code the names of the tables I never way updated, I just dont know where to put the code. Can anyone help me?

TIA,
Sandi.
