Recently I discovered a file named _BVOE9~A in my home directory. The interesting thing is the file does not show up in a 'ls -a' nor when booting into Parted Magic and mounting the partition to do a 'ls -a'. The file however does show up when I share my home partition with my Windows 10 virtual machine.

The file appears to contain debugging info for KDE. See below.

Does anyone know what this file is and why it and a second several months older do not show even when using a Linux boot DVD? (My Parted Magic boot disk was created on openSUSE 13.2 prior to reformatting my system partition for 42.3)
