Apr 27, 2025 by ADMIN 76 views

Problem Scope and Details

The issue of transferring files to Fastmail and Koofr WebDAV mounts resulting in 0kb files is a problem that has been encountered by users of the DAVx⁵ app on their Android devices. This problem is specific to the use of DAVx⁵ and the WebDAV protocol for accessing and transferring files to Fastmail and Koofr cloud storage services.

Problem Scope

The problem scope of this issue is limited to the use of DAVx⁵ and the WebDAV protocol for accessing and transferring files to Fastmail and Koofr cloud storage services. This means that the issue is not related to other cloud storage services or file transfer methods.

App Version and Android Version

The app version of DAVx⁵ being used is the latest available version, which suggests that the issue is not related to any bugs or issues with the app itself. The Android version being used is Android 14, and the device being used is a Samsung S21 FE with One UI 6.1.

Steps to Reproduce the Issue

To reproduce the issue, the following steps can be taken:

Create Fastmail or Koofr WebDAV mounts for Android phone.
Try to copy a file to them using an app that supports Storage Access Framework, e.g. Aqua Mail, Genius Scan, Adobe Scan, X-plore.

Actual Result and Expected Result

The actual result of attempting to transfer a file to Fastmail or Koofr WebDAV mounts using DAVx⁵ is that only 0kb files appear at the destination. The expected result is that the entire file should be transferred successfully.

Further Information and Workarounds

Further information about the issue and potential workarounds have been gathered. It has been found that using Storage Access Framework WebDAV for Koofr added by the official Koofr app for Android, as a destination for file transfers, does not result in this issue. This suggests that the issue is specific to the use of DAVx⁵ and the WebDAV protocol.

Additionally, it has been found that using non-Storage Access Framework WebDAV that is not handled by DAVx5, as a destination for sharing a file in Android, does not result in this issue occurring for me, with Fastmail or Koofr. This suggests that the issue is related to the use of DAVx⁵ and the WebDAV protocol, rather than the cloud storage services themselves.

Possible Causes and Solutions

Based on the information gathered, it is possible that the issue is caused by a bug or issue with the DAVx⁵ app or the WebDAV protocol. However, it is also possible that the issue is caused by a problem with the Android device or the Storage Access Framework.
