Hi Tim,
I have problem with some customers that have to send data files frequently
to another location.
They soffers for big data files (encrypted) that cannot be compressed as the
equivalent not encrypted, so transmit files are much expansive.
How I can revert, at runtime, encrypted files to normal files?, Can I obtain
the original files in security and automatically only altering tables
deleting the password? (My zip utility don't comprise anything, there is a
component that can work better; I don't think due the nature of encrypted
files).
Naturally I intend DBISAM 4.

Thanks in advance!!

The only way to do so in "bulk" form is to alter the table and remove the
encryption, send the files, and then re-apply the encryption.  Of course,
you have to be careful when doing this to avoid exposing tables on disk in
an un-encrypted form.

An alternate way to do so would be to stream the table to a temporary file,
send over that file, and then load the stream file into an empty table on
the other end:
