Special files (local upload only)

Other than media files, 2 special file types can be uploaded *using a local connection*, specifically:

  • ZIP files

  • APK files

Zip file

The zip file can only contain multimedia files. Multimedia files in a folder structure or non-multimedia files (including zip files) will not be processed by the device.

A zip file containing only multimedia files in the root (e.g. exported zip files from kiosk- or survey datasets) can be uploaded in one go to the device. Tap the upload button to select the zip file and upload it to the device.

Once the upload finishes, the zip file will be unpacked and the multimedia files will be shown in the multimedia folder. There could be a little lag between the upload and the media files being shown in the list, depending on the size of the content in the zip file.

If a multimedia file already exists on the device, it will be overwritten.

APK file

To install applications on the device without using the store, an APK file can be uploaded to the device to run it.

Tap the upload button and select the APK file on the connected device. Tap the Upload button to upload the APK to the device. This will show the installer on the device where the user can choose to install the software on the device.

It is highly recommended to only upload one APK file to the device at a time. Otherwise, multiple installation windows will be stacked on top of one another.
