.rzk File Extension

Developer: Red Zion
File type: Red Zion Notes File
You're here because you have a file that has a file extension ending in .rzk. Files with the file extension .rzk can only be launched by certain applications. It's possible that .rzk files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .rzk file?

Files with the RZK extension contain details associated with the encrypted data stored in files saved in the RZX format. These RZX files are text documents encrypted using the Red Zion File Crypt application. Users can encrypt the content of their text documents and secure it by generating a unique password using this application. The Red Zion File Crypt application generates a password for a text document, and this is done right after it integrates its encryption functionalities into the content of the text document. This text document is then saved in the RZX format, and an RZK file is then created by the Red Zion File Crypt program. This newly created RZK file is associated to the corresponding RZX text document and is stored in a secure directory. Upon clicking a text document in the RZX format, the user will be prompted to enter the correct password to access the content of the text document. When the user enters a password, the Red Zion File Crypt application then finds the RZK file associated to the RZX file, in order to retrieve the password details generated for the RZX file. When the password is verified, the user can access the content of the RZX text document. If the user enters a password that does not match the password details stored in the associated RZK file, then the Red Zion File Crypt application prohibits the user from accessing the content of the RZX text document. Even if popular text editors like Microsoft Notepad and Microsoft Wordpad can be used to open and view files in the RZK extension, the actual password details are not accessible to the user in this RZK text document, since the Red Zion File Crypt application also encrypts the content of these RZK files.

Red Zion E-book

Red Zion E-book

Red Zion E-book is an application that is classified as a document viewing tool, and this software is embedded with compatibility support for widely used versions of Microsoft Windows. The Red Zion E-book program is integrated with a set of features that can open, display the content and access certain functionalities implemented into an RZB file, which is a digital document format used by some Slovenian ebook authors. Some of these RZB digital books are encrypted with copy protection keys, and these security tokens are stored in files in the RZK format. This means when a user wants to copy the content of an RZB file that is displayed in the main window of the Red Zion E-book's Graphical User Interface (GUI), this software initially checks if there is a security token that encrypts the content of the RZB file. If this program finds a security token, it requests for the correct set of keys from the user. When the user supplies the correct security keys, this software allows the user to copy the content of the RZB file. It will however deny copy access if the user provides an incorrect security key or if the user does not give one. Red Zion E-book is also known as Red Zion E-knjiga.
Microsoft Notepad

Microsoft Notepad

Notepad is a basic text editor used to create plain documents. It is commonly used to view or edit text (.txt) files, and a simple tool for creating Web pages, and supports only the basic formatting in HTML documents. It also has a simple built-in logging function. Each time a file that initializes with .log is opened, the program inserts a text timestamp on the last line of the file. It accepts text from the Windows clipboard. This is helpful in stripping embedded font type and style codes from formatted text, such as when copying text from a Web page and pasting into an email message or other “What You See Is What You Get” text editor. The formatted text is temporarily pasted into Notepad, and then immediately copied again in stripped format to be pasted into the other program. Simple text editors like Notepad may be utilized to change text with markup, such as HTML. Early versions of Notepad offered only the most basic functions, such as finding text. Newer versions of Windows include an updated version of Notepad with a search and replace function (Ctrl + H), as well as Ctrl + F for search and similar keyboard shortcuts. It makes use of a built-in window class named edit. In older versions such as Windows 95, Windows 98, Windows Me and Windows 3.1, there is a 64k limit on the size of the file being edited, an operating system limit of the EDIT class.

a word of warning

Be careful not to rename the extension on .rzk files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .rzk. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
