Hi.
If I was concerned about securing database files that my programs use, I would want the system to be encrypted.
Before using an unfamiliar software product to make a major system change, it is advisable to make a perfect backup of the system.
Are you comfortable with removing a hard drive from your machine and replacing it with a similar hard drive?
You could do this:
* Make a backup image of the internal drive, saved on an external drive.
* Replace the internal drive with a new internal drive.
* Restore the backup image to the new internal drive.
If the computer operates as it did before the drive replacement and the copying, this probably demonstrates that you made a good backup. If not, removing the new internal drive and putting the original internal drive back in place is likely restore your computer to its condition before the drive replacement and the copying.
If you find that you succeeded in copying the system to the new internal drive, you may leave it in the machine for a while and experiment with encrypting the operating system.
Here is a hint: If you have a Windows system on a drive with GPT partitioning, it boots by standard UEFI. If you encrypt the system on such a drive without adjusting the partitions and the bootloader files required by Windows, do not expect Diskcryptor to boot that drive afterwards.
You can look at the machine's boot mode in the BIOS settings menus. For most PCs, the menus can be accessed during startup if a certain key is pressed, which commands the computer to launch a built-in settings manager instead of launching the operating system.
Here is where I have discussed experimentally changing a system that requires a standard UEFI startup, so that this requirement is removed, and Diskcryptor can start it:
