     1.1 Description
-------------------------------------------------------

ULTRA Files provides a fast and secure encryption for all your files. The files are compressed and encrypted using the ULTRA v1.0.3 cryptographic algorithm

If desired you can set a Private Crypto Module (PCM) to create an exclusive user group.


-------------------------------------------------------
     1.2 System requirements
-------------------------------------------------------

2 Mb free space on hard disk
16 Mb memory
Windows 98 or higher


-------------------------------------------------------
     1.3 Encrypting Files
-------------------------------------------------------

Select a file an click 'encrypt'. If there's no key set, you will be promt to enter a new key.You can overwrite the original file or select another target file.

To enter a key, all character are allowed. We recommand at least 6 character. As you enter the key you can see the key quality below. Longer keys or using small and capital chars, together with signs, will provide higher security. Key that use only one sign (for example: AAAAA) or keys, smaller than three signs are not allowed.

Once encrypted the file will have the extension ucc and the original extension is included in the encrypted file. Without the key the original filetype cannot be retrieved.

You can open or start the file by selecting the 'Open or Start' menu. When the sourcefile is picture you can take a quick view by clicking the file's icon in the window or by selecting 'Quick View'


-------------------------------------------------------
     1.4 Decrypting Files
-------------------------------------------------------

Select a ucc file and click 'Decrypt' . If there's no key set, you will be promt to enter a new key.You can overwrite the original file or select another target file.


-------------------------------------------------------
     1.5 Setting the Private Crypto Module
-------------------------------------------------------

To create an exclusive usergroup you can use the Private Crypto Module (PCM). All changes to the PCM can be made in the main menu. This code must be at least 8 characters. Once set, this PCM will be saved and used each time the program starts.

If a PCM is present, you can disable it temporarely to encrypt files towards users outside your usergroup. This can be done by unchecking the PCM at the bottom of the window.


-------------------------------------------------------
     1.6 The options
-------------------------------------------------------

In the Options window you can select the default folder to select files .

If 'Enter new key for each file' is checked, you must enter a new key for each new file you have selected. If not checked, the current key will be used until the program ends or another key is entered.

If desired you can register the ucc filetype in the Optionswindow. Next time the computer starts, the ucc file will have it's own icon and you can start the program by clicking an ucc file.


-------------------------------------------------------
     1.8 Known problems
-------------------------------------------------------

Using ULTRA Files to encrypt or decrypt files can cause problems when the filesize exceeds the CPU's available memory, resulting in extreme slow proccessing due file swapping or even program lockup. This is due to the fact that the file needs to be loaded entirely for proccessing. These problems does not occure when creating USD's because they are continuesley loading and saving the data to another target during file proccessing.
