Hello,

You didn't mention that what type of file you will downloaded. Because it can be documented file, ppt, photo or video etc. Generally we will get the downloaded file from download app. If you can find the file then check maybe it's there but the name is different.also if it's save another site may be you can't notice. And another thing sometimes in computer or laptop many app can't downloaded. So you have to check all of this.

All the best.
