Importing STL files from other places

After setting up my new Creality machine and getting it to print half of the test models, I wanted to broarden my horizens a little and print something from ‘Thingiverse’ instead. So I went to File, clicked on import, clicked the ‘Model File’ on the bottom and it went too my desktop. It probably did this because that was the last place I’d been before. I re-directed the ‘Model File’ window to the downloads folder, where I downloaded a file from Thingiverse an hour before. But when I clicked on the file, it came up blank. It was only when I opened the file, took out the STL file, put it on the desktop and tried to import the file a second time, import showed the STL file and I imported it into Print.
My question is: why couldn’t the import window find the STL file when I first found the folder where the STL file was located. Eventually, I set everything up and the ‘Rack & pinion’ is being printed as I’m writing this post. So, I’m pleased I eventually found an STL file from outside the software (Thingiverse) and imported it, but in a round about way.

Thanks

Normally files from Thingiverse etc. are in a zip file so you will have to extract the files first. They should then show up in Creality Print.

Thanks Gary
I’ll have to stop asking stupid questions like this. btw, the ‘Rack & Pinion’ Turned out OK but the pinion (Gear) part is a bit distorted where the printer printed it on top of the rack and when I eased it apart, it broke the that side of the gears. It runs OK but it looks damaged on one side.
Can you put this Rack & pinion STL into Tinkercad and seperate the Pinion from the Rack and have Creality print it in two parts instead of one.

As always, best regards

Michael.

What about the split function in Creality Print? Short key is press c then move the plane to where you want to split it. I think you can put a split plane in by selecting a face. I don’t know TinkerCAD, I use Inventor, but I don’t know if you can split an STL in something like that (could if it was the STEP file). Autodesk Meshmixer should be able to do it, I’ve certainly trimmed STL files with that.
