Is there any way to bypass the password to open clarion .dct file?

I tested adding a password to a DCT in 11.1 and viewing the Hex it did Not appear to have been encrypted.

You might be able to reverse engineer it using a Hex compare tool to see where the password is stored and a Hex editor to remove it. Create a simpler DCT with 1 file AAA and 1 field BBB. Copy it and add a password XYZ then compare hex.
