Why can’t I unzip files in Vista?

September 12, 2007 at 9:29 am 46 comments

In Windows XP, you can unzip files by double-clicking on it or by right-clicking on it and using the context menu. When I tried this on Vista, the menu was not visible? Did Microsoft remove that feature?

Apparently, I installed ZipGenuis 6 recently but uninstalled it quickly after it had difficulty with some self-extracting archives. When the program uninstall, it did not restore the default association for Zip files. As a result, I can no longer unzip files!

In most cases, you can restore associations by selecting open and the picking the program you want to associate with that file type. Unfortunately for you, the Windows zip file is not a program, but a shell extension. If you type in a command line:

ftype | more

You will see an entry for CompressFolder and it calls a shell extension dll.

To restore the functionality, you need to do the following:

  1. Select the Start Menu, select Start->Accessories. Right click on the Command Prompt and select Run As Admin. You need to be admin to change the association. You will be prompted to enter your admin password. Enter it and press return.
  2. In the command line window, type in the following command

assoc .zip=CompressedFolder

Now when you right-click on a zip file, you should see the familar extract menu again.

    I accidentally associated zip files with my paint program using the “open with” command.

    I’ve tried the fix you recommend but the file is still associated with my paint program.

    How do I re-assign these files to be opened with Vista?

    Didn’t work for me – it remains associated with a programme that can’t open it (Adobe Reader) and I can find no way to un-associate it with this programme which keeps trying to open it when I click on a zip file.

    Martin, I think this is a totally different problem. The problem describe occur because when the zip program is uninstall, it does not put the OS unzip back. In your case, you probably associated the zip file with adobe reader. To fix the problem, rightclick on the zip file and select open with, then select your zip program (such as 7zip) and check the box “always use selected program…”

    Hi i Just tried your solution to the zip problem but it isn’t working. I still cannot unzip compressed folders or even make a compressed folder. This is a big problem for me so does anyone know another solution that will work??

    Thank you so much for your advice on how to unzip files in Vista! I was facing the prospect of purchasing a popular unzip programme when I found your post.
    Keep up the good work!

    I can’t unzip my file either. I have a compressed zip folder but there’s no “extract all “option. I tried your solution but it didn’t work. Can anyone offer any solution? Thanks in advance.

    Thanks so much. My version of Vista (Premium) required me to follow these steps: 1.) click Start; 2.) click Accessories File Folder; 3.) Click Command Prompt Program; 4.) Type in: assoc .zip=CompressedFolder (as you posted above) and hit return.

    My unzip feature worked immediately. I am grateful for your help. Have a great day. : )

    I need to do this – if I follow 13 (I am vista premium,the proceedure seems simpler without runing or using passwords – no right click on Command Prompt, just the left click – but, when you say hit return, what is that? Thanks …. looks like I’m getting close to unzipping some videos – believe me, Vista help was no help –

    I tried this on a student’s laptop and it didn’t work either. The problem program had been removed.

    I noticed that after trying the ftype command it lists CompressedFolders being associated with Explorer.exe

    So using the old (Windows XP) way, I simply chose the file, right-click and choose “Open With…” and choose the Windows folder and find “explorer” (or “explorer.exe”)

    This will let you open the zipfiles by double-clicking… but it seems not to restore the Compressed Folder icon. But at least it works.

      Sherry,

      Unless you plan to uninstall winzip, you probably don’t have a problem. This problem were a while back, so I am guessing that they fixed the install issue by now.

    go to this site and look for the zip download in the BOX. Download it to you documents and run it. it will fix your zip file association automatically……………..If you have fixed it already, Take note of it and maybe you can help some one else that may have a similar problem—————-http://www.winhelponline.com/articles/105/1/File-association-fixes-for-Windows-Vista.html

    No. 15 Thanks a million. The command prompt didn’t work for me, maybe because I have Vista Basic , so I tried your “Windows XP way and it works like a charm. Thats why I love XP it has a fax console in the home edition and working with it is not as confusing as the upgrade Vista. Thank you Rick.

    HAHA! I found it! For vista users who could only get zip files to open through windows explorer, find a zip file, right click on it, open with, select “Choose default program”. Now, set the file you are looking for from program to “all files”. Now, for the location at the top, type “%systemroot%” and hit enter. Open the folder “system32″, and scroll all the way to the bottom, select “zipfldr.dll” and then hit open. The highlighted program should be “Compressed (Zipped) Folders”. Hit ok, and your pc is back to normal! Good luck!

    so frustrated. I tried all the solutions above. None works!

    #33 might work. I found the file “zipfldr.dll”, but I cannot open it.

    then I hit a link to PC MightyMax 2010. If found 304 errors in my vista. Unbelievable!

    Just so frustrated!

    @ Okra

    Sorry to hear about your problem. You can’t just open it. You need to find a zip (or compressed) folder. Right Click, Open With, Choose Default program, and follow the rest of the instructions from 33. When all else fells, this should work. If not, get a mac!

    Works just like #21′s solution did, but with my ZIP problem, it was easier to figure out how to get the download to work properly.
    http://www.vistax64.com/tutorials/65254-zip-file-support-restore.html

    I suspect that the above is a fairly new fix. It worked brilliantly.

    Make sure to restart your computer. When you do restart, your files should be zipped if they had originally been zipped!

    I finally managed to get the right-click menu to display the ‘extract all’ option, and then got the message: “the compressed zip folder is empty. Before you can extract files you must copy files to this compressed (zipped) folder.”
    There is no way that the folder is empty – it’s 1.5 Mb in size. I’ve tried it on antoher computer running XP – same result.
    What now?

    I know this is old but I just had the same problem. Only thing that worked for me was #33, although the instructions did not exactly match up, but the basic concept worked: Right click a zip file-open with-choose default program-choose zipfldr.dll (which was hard to find, was not located in System32 folder, or at least not visible….search is your friend) and now compressed folder icon is available as a choice!
