as the question lacks further information here some basic info:
In Minetest you can make screenshots by pressing the [F12] key on the keyboard.
The screenshot is saved to the bin folder by default. That is the same folder the program executable resides in.
If you specify another folder in the minetest.config you may have to precreate it manually as the screenshot function may fail silently without warning if it fails to find a valid folder.
Information that might make answering easier would be:
which operating system?
1.Linux
2.Windows
3.Android (tablets, mobile telephones)
what kind of installation?
1.System wide
(parts of minetest may be spread to different places all over youre system as program data is seperated from user data. default in most linux builds)
2.Run-in-place
(all files are kept in a single folder tree. default in most windows builds)
and of course, what version of Minetest are you using? (including stable or dev)
