Jet compact utility

Question

Hello

Any idea why this download is not signed with a code signing certificate by Microsoft?

https://learn.microsoft.com/en-us/office/troubleshoot/access/jet-compact-utility-download

And, there's a password protected mdb database that I need to compact, please advise the difference between these?

JetComp.exe -src:"C:\src.mdb" -wMYPASS -x -dest:"C:\dest.mdb"

and

JetComp.exe -src:"C:\src.mdb" -wMYPASS -dest:"C:\dest.mdb"

Its help indicates:

-x Encrypt Destination Database

Encrypt means password protection?

If so, my source database is already password protected, but using both commands will make a new password protected database, so they should be identical but are not, confused :(

Thanks.
