From the 4.45 release announcement ....

"Warning If you are using local DBISAM sessions to directly access shared databases on a file server, you need to make sure that all client applications that are accessing the data are either updated to 4.45 or have their pre-4.45 TDBISAMEngine LargeFileSupport property set to True. Failure to do so can cause the local DBISAM sessions to not see each other's locks, which can lead to database table corruption."

How/where would I do the "pre-4.45 TDBISAMEngine LargeFileSupport property set to True" bit so I can ensure my app can safely share data with a long with other older applications

Thanks,PhillipH

PhillipH,

That setting is available in older DBISAM versions so those versions
have to set it to true either by (1) dropping DBISAM Engine component on
the main form and set the "LargeFileSupport" property to True or (2) in
app startup code set "engine.LargeFileSupport := true" (you need
dbisamtb unit in your uses clause).
