This is the dumbest fucking thing I’ve ever heard of. I’m not buying any keyboard or laptop that has this key.
Which is exactly what people said about the Windows key.
Now it’s all but impossible to buy a keyboard that doesn’t have it. Worse, most of us use it without thinking.
Sure you can call it Super if you like, and even have a Tux key-cap on it, but there used to be a literal gap between the Alt keys and their Ctrl brethren in the lateral directions away from the space bar, and those days are long gone.
There’ll be the niche users who stick with old keyboards without this new key, just like there are the die-hards who have stuck resolutely to the old IBM keyboards and the like from pre-1995, but if you want a new keyboard?
Gonna have to shell out a small fortune for a custom build or make do with that dumb new key.
(Shoutout to the Context Menu key which went as unmentioned in the above as it goes unused in day to day use, despite having been included with its Super cousin since day one.)
You could run an offline
fsck
to make sure it’s not being caused by disk corruption or something. An offline malware scan at the same time wouldn’t hurt, however unlikely. (That is, boot from external media so you know the drive’s not in use.)The
file
command might be able to identify it if it’s of a known format, but if, as you say, it’s all zeros that won’t be particularly fruitful (it’ll just say “data” if a test on my own computer is anything to go by).Or you could
lsof | grep theweirdfilename
to see if any active processes are using it, not that this would show up if it was malware (which is unlikely, especially if you did that scan earlier).If, as you say, it’s all zeros, you could just
bzip2
it (or similar) if you don’t want to delete it for whatever reason. That way if something complains you could uncompress it again.That said, if it doesn’t show up as useful and isn’t fixed by any of the above it’d probably be OK to delete it.
