1. Using Windows Explorer, locate the first file you want to zip.
2. Right click on the file and select “Send To” and “Compressed (zipped) Folder.” This will create a new compressed folder with the same name as the file, except with the extension .zip.
3. Right click any other file you want to compress and select “Copy.”
4. Right click on the compressed folder you created in step 2 and select “Paste.” The copied file was pasted into the compressed folder. Repeat this until your compressed folder contains all the files you want.
5. Right click on the compressed folder and select “Explore.”
6. In “File,” select “Add a Password.” Enter the password and confirm the password.
B. If you have an earlier version of Windows:
1. Download a zip utility. WinZip is very popular, and an evaluation version is available free.
(Other zip utilities are here: »www.freedownloadscenter.com/Util···ilities/)
2. Using Windows Explorer, locate the first file you want to zip.
3. Right click on the file and select “WinZip” and “Add to Zip File.”
4. In “Add to Archive,” enter the path and name you want your zip file to have.
5. Click “Password” and enter the password you want the zip file to have.
6. Click “Add.”
7. On the WinZip window that appears, click “Add” and select any other files you would like to add to your zip file.
8. When you are done, select “File” and “Close Archive.”
If you are creating a password protected zip file for the purpose of sending a virus to an anti-virus company, use the password “infected” and state “the password is ‘infected’ ” in the email the zip file is being attached to. In this special case, the password protection is simply to prevent the virus from tripping alarms and being disinfected before it reaches the anti-virus company.
Some tools for making "password protected zip files" (compressed folders) may use the term "encryption" or "encryption key." Encryption key is technically the more accurate description. They are talking about the same thing, though.
(Don't worry if an unencrypted copy of the zip file is created in your TEMP directory when you enter the password. The work-file will be deleted by the zip utility when it terminates. If your zip utility fails to do that, contact the zip utility vendor. - Keith2468 2008-07-21)
Any idea what encryption algorithm this uses, and how secure it is presuming you use a good password?
this works well but not on movie files..(.mpg)the files just open the same?
Only one problem with this (it seems)... When you double click the file to open it, and yes, enter the password... It creates a copy of the file (un protected) in the local/temp directory... Have you noticed this? Is there a way around that (feature?)
This is just what I needed. Thank you soo much!!
RE "A" above Is there anyway that the cmd unzip can be used to retrieve the passworded file?
THANK YOU for the help!!!
this is good! excellent info they provide and its really works... Thank you...
thanks, its very useful. keep posting.
This was exactly what I needed in a short and simple response. Thank you
I like the description, but it takes ages to add a password to a zipped file containing a large number of files. Is there any quick way to add a password to zipped file only? I do not understand why the Windows XP's utility adds password to each and every file. In my opinion, this is an inefficient way of adding a password. There should be something better than this.
ya... working good... thanks....:-)
Many thanks. It works fine.
Just tried the steps in Section "A" but it does not work. It allows the zip file to be opened without the password; the password is only asked when an extraction is attempted.
Thanks! I kept trying to use the password function in Winzip, but it would not stick. This way worked. Don't know how you knew the syntax of these steps, but thanks again!
great straight forward advice thanks
thanks a lot, to me in my workplace, where no third-party software allowed, this knowledge is very helpful...
Thanx wery much
thank u so much..... :)
Among other zip utilities I can recommend PeaZip http://peazip.sourceforge.net (Windows, Linux) as it has strong AES encrypytion for 7z and zip files, and two factor authentication (use a password alongside a key file). It also seems not using temporary files and in any case it has an integrated secure file deletion utility to erase any leftover.
