i read the help file of the program power achiver... it reads:
To start the tool, select "Encrypt File" from the "Tools" menu.
At the Encrypt dialog box, you will need to do several things:
"Select Source File" - select the file that is going to be encrypted.
you can select any file you wish, but we recommend using archives because PowerArchiver can then intelligently handle them
"Select Destination File" - enter the name and location of your future encrypted file.
"Encryption Method" - PowerArchiver has 5 different methods of encryption available with Rijndael - AES (default) being the most secure. We recommend using Rijndael for encryption since it has been elected as a new Advanced Encryption Standard (AES). Click here to find out more info on Rijndael from the AES website.
"Delete original file after encryption" - when checked, file that was encrypted (source file) will be deleted after encryption.
After you have selected the options, click "Encrypt" to finish the process and encrypt the file. PowerArchiver will then ask you for a password and you will have to enter it two (2) times.
Please note that it is very IMPORTANT that you do not forget your password. You will NOT be able to use the file if you forget the password. There is no way you can recover a forgotten PAE password.
Because PowerArchiver does not compress data in PAE files, we recommend using PAE together with an archive format of your choice for best results.
i think really no hope liao...
