    Herr Koehler,

    I am a user of the pro version of the zip viewer. Thank you for a good product. Many of the zips I open have embedded zips. I can’t recursively open them. Does the app provide such an ability; and, if not, is this feature planned in a future release?

    Thank you in advance.

      Thanks for using Zip Viewer Pro.

      Unfortunately, Zip in Zip is not supported yet, but I will put it on my feature list for a future release.

      Kind regards,

    Hi, congratulations for the great Work in this app! It is simple the best! Allow me to see photos inside zip files in fullscreen mode, without extracting then! Absolutelly perfect! The fullscreen is perfect,clean and fluid.
    The only concern is That there arent a system to tag the zip files or group then in folders… Ex: folder e-mail (zip from e-mail), folder A (Zips from site A), etc
    “This file i already saw, That one didnt”
    Maybe we wait for something like That in future updates?

    Your app does not offer viewing of .mov files zipped from camera roll.

    When Zip file of two or more .mov files is opened in your app and the file is touched to view, all that happens is your app crashes.

    • Author
      oliko 2 years ago

      I did the same with two .mov files but could not reproduce the issue. I was using an iPhone 5 with iOS 8.3. (see screen cast)
      Have you considered an upgrade to the latest iOS version. Maybe that would solve.
      How big is the file size?

  6. John B 2 years ago

    zipviewer does not show up when I tap and hold a zip file attachment in my email. I cannot figure out how to use it now. It used to work with no problem on my iPhone and iPad now neither works.

      Should work as before. Can’t figure this on my device. May be a reboot of your iPhone or reinstall the app will solve the issue.

    successful download of 2 zipped files of MP3 music. How can I move them to or access them from another app?

    • Author

      touch on the file to start playing. Then in the lower left corner is the share button to send the file to other apps on your device.

  8. MG 2 years ago

    I was able to open my “password protected” zip file from Google drive, which is great! The issue is that my zip file contains another “password protected” zip file and there was no way to open that up. Does this mean that this app only opens one level of zip and not multiple levels of zip files?

    • Author
      oliko 2 years ago

      You cannot open zip in zip yet. A workaround would be send the included zip via email to yourself and open it again in zip viewer. Will consider this in future updates.

      • MG 2 years ago

        I tried your workaround. I unzipped the parent zip file and saved the child zip file to google drive. Once the upload to google drive was complete, I tried to unzip the zip file and it failed with error : “Possibly not a zip file”!

        So either the parent password protected file’s unzip was errornous or some weird issue with the child file’s unzip. The second unzip didn’t even ask me for the password. Just threw the error.

        • Author
          oliko 2 years ago

          This error message appears in case the file was not detected as zip. The file must be PKZIP complient. An AES encrypted file does not work.

    I tried to open Zip files which are attached to an E-mail using the iOS mail app. I tapped on the attachment and a new window appears showing name and size of the Zip file. But nothing happened when tapping on the share symbol. The same behaviour occurred when using the Telekom mail app.

      You have to touch and hold (long touch) until the open in Dialog appears. Then choose zip viewer from the app list.

      • Udo Krüger 2 years ago

        Thank you for this hint. With some attachments it woks, with other not. Even when the list of apps appears, the Zip viewer is missing.

          If the extension is .zip, Zip Viewer should show up. The file must be PKZIP compliant. 7zip or similar formats are not supported.

  11. Rachel Colenda 2 years ago

    I downloaded a zip file and it shows up as the only thing on the list in the app. When I click on it, however, nothing happens for a few seconds, then the whole app just cuts out back to my home screen. Every time. I am very frustrated. How am I supposed to access this file?????

    • Author
      oliko 2 years ago

      Does this happen to all zip files or just a certain? Either the file was corrupt or no regular PKZIP complient file.

    • Nikorah 2 years ago

      Never mind, it suddenly started to work, thanks. It would be nice to have instructions to read like “hold the file down for several seconds to open”. Why do u have to press on it for so long? My other app that is similar opens right up with just a tap. .?? Thanks for the app!

      • Nikorah 2 years ago

        Ok, now it works by just tapping lightly on it., how weird is that? Sorry, I would delete my original question but I don’t see that option. The first file was quite large perhaps that’s what messed things up?

    Can you please advise soonest!!!

      Should be working. Did you change your apple id? Try logout ans login again.

  17. Dick Copra 2 years ago

    same comment as Rachael September 2015. Can not get my zip files to view no matter how long I hold the button. Program just exits. If the file is not compliant could you not give some sort of status before program just dies?

    Bought program to see my son’s wedding pictures. Seems like a waste of money, hope I am wrong.

    • Author
      oliko 2 years ago

      file extension must be “.zip” Please check if that’s the case. White spaces also before the dot sometime can cause this issue. The open in dialog is controlled by iOS not be the app itself. You could also try to restart your iPhone.

      • Dick copra 2 years ago

        File is zip. Other programs were able to process this after I gave up. Could not be file type. Old school programmer, believe that you should always trap failures and give the user an error message – not just crash.

      Standard PKZIP complient zip files should be working. Touch and hold on the zip file in the email and then choose zip viewer in the open in dialog to open the archive.

  29. Dave C 1 year ago

    AAAA+ This is a great app for my iPad . I take online bluegrass lessons and need to download the sheet music to my iPad . I was using Dropbox and it was a hassle because Dropbox could not open the files. I had to email them to my laptop and open the sheet music there. With Zip it takes just seconds to get the files and open them. I can store all the music there and keep it on my iPad. Now I don’t have to deal with Dropbox .

    Is there an easy way to transfer my files from the free version to the pro version?

    • Author
      oliko 1 year ago

      Yes, connect your iPhone or iPad to your mac (better USB) and open iTunes. Both versions free and pro need to be installed on your device. Go to the iTunes file sharing section (select you device in iTunes). Click on the free version and download (save as) the folder “workbooks”, which should have appeared in the box documents on “Zip Viewer” on you computer. Then click on the pro version and push the button add to, choose the (beforehand downloaded) “workbooks” folder. Important: choose “replace”, when the dial appears. Restart the pro app and the files should appear as in the free version. Note: If you have already files in the pro version this procedure will delete them.

    • Author

      The app is only asking for a password if the zip file itself is password protected. Ask the one who sent you the file.

  33. ersnotoltor 1 year ago

    By default the iPhone has issues with opening zip files, especially if the file includes something more than just a PDF. You can open a zip file on your iPhone and use the files with a free app.

      Then the zip file is password protected itselfs. You need to enter this password. The app does not require a password by default.

    When I go to mail and try to open link in. The zip viewer icon is not there? Why is this? I have an iPhone 6s and on iOS 9.3

    • Author
      oliko 1 year ago

      I just tried with the lastest iOS 9.3.1. When you have an email with a zip file attached to it, you have to touch (and hold) on the file icon until the open in dialog appears. This dialog should show all apps that are able to work with zip files including “Zip Viewer”. May be that you have to scroll to the right. If you just normal touch on the icon iOS tries to open the fils itself. In some cases just the name is displayed. If that’s the case you could also touch on the share button in the upper right corner to get the open in dialog. But the long touch on the icon is the faster way.

      The app is made for unzipping zip files and works only with regular zip files.
