A bug has been discovered in Windows 10 which causes files copied from one location to another on a PC-connected Android to vanish completely if the built-in file manager File Manager is used for the operation.
The issue affects only files that are being moved or copied from an Android folder or storage device to another location on the same Android phone or tablet using an MTP or PTP USB connection, and it does not seem to impact copying data on a Windows 10 PC.
This means, when users connect an Android device to a Windows 10 PC and try to move files with File Explorer from the phone to an SD card or vice versa, this will result in data vanishing completely. The transfer appears to be working, but the files do not reach the destination folder, with no recovery possible for the time being.
The bug has been confirmed on Windows 10, with both Windows 7 and Windows 8 working correctly as of now. Also, there are a number of Android phones which appear to be affected, including OnePlus and LG models, Google’s Nexus and Pixel, HTC 11, Nokia phones, and several Xiaomi and Sony models. On the contrary, Samsung’s and BlackBerry devices are working correctly, user reports indicate.
While Microsoft has not yet acknowledged the bug problem, the easiest way to save your data right now is to create a backup which will allow you to restore files at any given time.
Also, this issue is affecting only Android-to-Android transfers, a possible workaround is to copy data from the Android device to the PC first, and only then move it back to the new location on Android. This would be beneficial to the user as they would be creating a backup of their data as well at the same time.
