Working with Card Repositories
Concealer stores the information in a special file called a card repository. When you run the program for the first time, you should create a card repository.
The master password is the password that unlocks the active card repository. You can have several card repositories with different master passwords.
If you have several card repositories, only one can be active at any given time. When you log in, you open the last active one. You have an option to move the active repository to other location on your disk, or to activate another repository.
The size of a card repository depends on the content of the included file storage(s). If there is not enough room on your system drive, you can move the repository to another drive (internal or external).
