Inside my Documents folder there are a bunch of folders named with what appear to be hexidecimal numbers, eg. 01
, 1b
, 84
, aa
, etc. Often they're empty, but some have one or two files named with a hash: 5aaebbb6c171adb2159c17cd1c8e629fc774f1be.file
I assume the files are binaries because when I open them in a text editor they consist of rows of eight two digit hex values, 00eb babf 314c 00eb babf 3130 d3aa 0109
.
I deleted the folders a few weeks ago, but they slowly grew back.
My question is twofold:
What is writing these files/folders?
And because I doubt it can be diagnosed from my description, how do I monitor and figure out what is writing them?
I'm on 10.11, El Capitan.
I sometimes run a Windows VM in VirtualBox, I run Vagrant from the command line, and Docker as well. I run phpstorm, Spotify, uTorrent, Steam, Slack, Skitch, Xcode, Tunnel Bear. The list goes on. I guess what I'm looking for is a strategy or technique to figure out which application is writing.
