I used time machine to restore OSX. After restoring, there are zillions of .com.apple.backupd.mdmvXXXXXX files everywhere. XXXXXX is a seemingly random number, typically 7-8 digits long.

There seems to be at least one of these in each directory. Sometimes many.

The files are owned by root, and permissions 600. When I sudo cat them, I get XML similar to this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

I make the observation that the FileID matches the XXXXXX in the file name .com.apple.backupd.mdmvXXXXXX.

So what are these .com.apple.backupd.mdmv files? Should I do a recursive find and rm all these files on my hard disk? They aren't causing any harm in particular - but they replicate all over the place in dropbox and file sync and backup programs that I use.
