if your want zip file then you can try this:
Follow the steps below:
Go to
seven zip org in your web browser (Internet Explorer, Firefox etc).
On the home page click the top 'Download' link for '7-zip 4.57' (the file type is .exe).
Once the web page has loaded you may see a message window alerting you to a yellow Information Bar at the top of the page. To close the window click 'Close.'
The yellow Information Bar is a security measure which occurs when any software tries to install itself onto your computer. It requests confirmation that you want to download. To confirm click 'Click here for options' and then 'Download File.'
A new message window will appear asking whether you want to Run the download file or Save. Click 'Run.'
Another security message will appear asking you to confirm that you want to download the file. Click 'Run' to confirm.
The Setup Wizard will then ask you where you want to install 7-zip. As default it will have chosen your C:Drive. This is the default destination for applications so you do not need to change it. Click 'Install' to begin the installation.
Once installed close the Setup Wizard by clicking 'Finish.'
Encrypting a file using 7-zip
Once 7-zip is installed onto your computer you can use it to encrypt your files.
Follow the steps below:
Launch 7-zip using the Start menu (Start - All Programs - 7-zip - 7-zip file manager).
In the 7-zip file manager locate the file that you want to encrypt (the file manager will list all storage drives including your H:Drive).
Once you have located the file you want to encrypt, select it by clicking it once.
With the file highlighted, click 'Add.'
This will open a new window called 'Add to Archive.'
At the top of the left column change the 'Archive Format' to 'Zip' using the drop-down menu.
At the bottom of the right column check that the 'Encryption method' says 'AES-256.'
Above it, type your chosen password into the 'Enter password' text box.
Directly beneath it, re-enter your password into to the 'Re-enter password text box.
Click 'OK' to close the 'Add to Archive' window.'
Back in the file manager you can now see the encrypted and zipped file. You can identify it by its icon which is of a folder with a zip through it.
You can now send the file as an email attachment but remember not to include the password in the same email.
