Sensitive Data

Password Safes

If you have data you want to protect from others you have a lot of choices. If it is about data which can be written down as "label" => "value" and both are text, then just use a password safe like yagodu or any of the many password safes out there. Some are simple, some can automatically fill forms and if you are stupid you will choose one which will store your password on the internet. Of course totally safe and secure.

Binary data inside password safes

If there is a small bit of binary data, consider using UuEncode and just put the created text as data in your password safe. Total Commander can UuEncode a file without problems, perhaps there are even password safes that can do that?

Mounting a file as a volume

If the data is mostly binary or you'd just like to have a directory/drive where you can put some stuff and it will be safe, perhaps try something like VeraCrypt. With VeraCrypt you can for example create a file with a size of your choice, if it is 1MB or 500GB, your choice, and then you mount it as a drive and have an empty drive at - for example - M: and then you put files there and unmount and nobody can access these files without the needed password or key file. You could put the key file on the USB-Drive you have on your key-chain or use a REALLY secure(=long, not weird) password and you are good to go.

You can put ANY type of file there. It might be a repository, your collection of totally safe-for-work photos or all the tax stuff you don't want your wife/man to see. Or just some games you don't want your children to play when you are not there.
