The DL link only points to a German version. Does it exist an English one? Couldn't find it!

The page is in german, the program lets you choose between german and english though (obvious in the screenshot) ;)

The tool does *not* delete anything that's on the target device. It only tests the free space.

@moronoxyd I agree

I found that
it Write-Tests to Free space only
so no file data will be lost or overwritten

a useful utility for finding the best SD card for the job
