Achievements

SpaceSharp has achievements, twenty-one of them, since 2.6. They change nothing about how the app works; they are there for the people who notice that their drive was read in four seconds, or that they have a file nobody has touched since 2014.
Where they show up
- A toast in the corner of the map announces a new one for seven seconds, with its name and what earned it.
- About › Achievements, or the T key, lists them all: the ones you have, with their hint, and the ones you do not, with only their name. Click a locked row to peek at its hint; click again to hide it.
- Collector, the last one, opens a small window instead of a toast.

The list
The names are not a secret; the hints are, until you earn them or peek. A few, for flavor:
| Name | Earned by |
|---|---|
| Speedrun | A whole drive read from the file table in under five seconds |
| The Long Way Round | Walking a whole drive folder by folder with the file table right there |
| Terabyte Club | Scanning a drive of a terabyte or more |
| Full House | Scanning a drive with 1% or less free |
| Mirror, Mirror | Comparing a scan with its own save |
| Collector | Every other achievement |
The rest: Night Shift, Encyclopedia, Deep Dive, Regular, Breathing Room, Spring Cleaning, Hoarder, Whale, Hall of Mirrors, Dust, Nothing Happened, Plot Twist, Tourist, Polyglot, Archaeologist.
Where they are kept
%LocalAppData%\SpaceSharp\achievements.json: the unlocked ones with the time each was earned, and the few counters some of them need (scans of the same drive, language changes). Delete the file to start over; there is no reset button on purpose. The pretend PC that the screenshots use (--mock) has its own in-memory list with four mild ones unlocked, so pictures spoil nothing and never touch your file.
