Greetings All;I'm in the middle pages of trying to build a voron 2.4 kit, a 3d printer. Definitely not recommended for beginners. Very poor assembly instructions. I've printed two versions of them, over 500 pages in dead tree format but am getting poor and often out of order or missing finishing touches, obviously the work of a designer who assumes this is the 50th such project the user has built and Just Knows what to do next..I have unpacked the .stl files to feed cura and they generally work, but each major section of the printed stuff also contains a Thumbs.db file. I'm not familiar with databases enough to know what to do, but being able to see whats in this file in thumbnail form would sure help me to build the next part I need. So what do we have that can display whats in these files, from a Chinese originator?File says this about one of them: Thumbs.db: Composite Document File V2 Document, Cannot read section info
Thumbs.db is a file generated by Windows OSes to speed up image previews. Users are not usually expected to need reading the file. On Windows systems such files are usually “hidden” (Windows does not follow the convention of the leading dot meaning hidden) such that they end up in all kinds of places where they are not expected/useful.
Unless you are looking to extract minature previews of some ofther files in that same directory, Thumbs.db may well be of little use to you.
Or in other Words: Whatever information you are missing and want to extract from there, is unlikely to be contained in the Thumbs.db.
Is there something that can display the contents of that?
Debian has a package called `vinetto`. When I tried it on some random `Thumbs.db` from Windows-originating files, it bailed out with
~~~
Traceback (most recent call last):
File "/usr/bin/vinetto", line 418, in <module>
print(" " + TNid + " " + TNtimestamp + " " + TNname)
TypeError: can only concatenate str (not "bytes") to str
~~~
That looks like a python2 -> python3 migration issue to me.
But: It extracted one thumbnail from the Thumbs.db that looks plausible.
If you must know about the Thumbs.db's contents, it might be interesting to
try this tool.
