Dale Derix | If I save a memory table to a disk file using .SaveToStream() in version 4.25..... will this disk file still be compatible with newer versions of DBISAM?
Thanks, Dale |

Raul Team Elevate | Good question and while i don't know the general answer i can say from experience that between different builds of same version it's OK (for example we have saved using 4.29 and loaded using in 4.36). The question would be around major file compatibility breaking changes - like 4.27 blob change - so for example saving in 4.25 and loading in anything newer than 4.28. Not sure about this one though i have a feeling Tim was smart enough to account for this - i know i can load into a table that has additional columns added. Usual caveats of using this still apply - it's all in memory so it might not be suitable for large tables - but that's not a compatibility issue.
