From there please select ArchXtract. Please enjoy using ArchXtract.

2021/8/11: 【Re-Post】Outlook attachment zip file cannot be unzipped on Android device

We apologize for the inconvenience caused to our customers for a long time. “Problem that Zip file cannot be shared to another application in Android Outlook” released on July 2 failed to open the encrypted zip from outlook to ArchXtract on Android device. We apologize for posting incorrect information. However, it seems that it is now possible to pass compressed files other than zip to ArchXtract. (Confirmed version: Outlook for Android ver 4.2123.2). This confirmed that the zip could be decompressed by transferring it to the PC once and recompressing it to 7z / tar / gz / rar (without password) as it is. If you can handle this method, please try it. We have confirmed the information that Microsoft is currently considering the restoration of the function to link the encrypted zip with other applications. Please wait for a while until it is completely resolved.

2021/6/17: Outlook attachment zip file cannot be unzipped on Android device

Currently, the encrypted zip cannot be decompressed on Android devices.

In Outlook on Android devices, there is a problem that the attached zip file cannot be shared with another application.

Therefore, it is not possible to share files from Outlook to ArchXtract or One Drive etc.

We are inquiring about this issue to Microsoft. Maybe this issue is due to the effect of the new feature release of Outlook.

We apologize for any inconvenience and will suspend Android support until a solution is available.

Please note that this issue depends on the version of Outlook and can be solved by downgrading Outlook if possible.

For reference, the Outlook version we have confirmed to work properly is 4.2041.3.

You can also save the zip file from PC to One Drive and unzip it with ArchXtract on mobile

or wait until Microsoft fix this current issue on Outlook.

※If you are in a hurry, please contact Microsoft directly when it is available.

2021/1/28: About startup crash on iOS 14.2.

The following issues have been resolved in iOS 14.4. Users who are having problems are encouraged to update to iOS 14.4.

After updating to iOS 14.2, there is a problem that ArchXtract does not start on some devices.

Specifically, it is a problem that occurs when installing an app via MDM such as Intune on a device with a relatively new CPU.

It is said that Apple and Microsoft are currently investigating jointly, so we apologize for any inconvenience caused to customers who are having problems, but please wait for a while.

As a sure workaround,

  1. Do not upgrade to iOS 14.2
  2. Download directly from the App Store, not via MDM
  3. Not used on modern devices

If you have any problems, please consider the possible measures above.
