Can't open a file I previously could.
There is a shared file (pdf format) which I could preview and open last week. But now I can't (there is a little car label to it now).
How can I open it again?

The upload will finish with no error, but after downloading, the file is corrupted.
This is a sample of corrupted video file:
Trados_Learning.mp4 (dropbox.com)
please help me to resolve this problem.
Hi Esikhoob,
The file not only has finished without error but is definitely not corrupted! It's another story that you cannot play this file in regular way, because of some upload mistake you have (error that's not reported, cosa Dropbox server cannot know about it). Just as an example see a screenshot of your video posted (on second 3 out of 23:34):
🤔 Is that you or whoever you took a shot of? 😁
Dropbox API (and all links produced) gives and expect raw data, not something else! Something you have ignored!!! How you got your data (movie) passed? 🧐

That's it. You still receive the same video, but "packed" in multipart form data. And since that's what you have forwarded, exactly the same you receive. Of course, most video players cannot distinguish packed video in such a way. Again, the keyword is raw data!!! Don't ignore it anymore and all will work. 😉
Hope this helps.

Hey there, fernandaverruck, I'd love to see what we can do about that!
I'm going to need some additional info, in order to provide you with the appropriate next steps.
Which platform do you use when trying to open the file? Do you get any errors?
If you have any screenshots of the icon you mentioned, or what you see on your end when this happens, let me know!
Keep me posted!

Hi! I tried both in the bowser and the app. Here is the screenshot.
I also tried to download. But it didn't work.

Hi fernandaverruck, thank you for the screenshot!
Do you access the file directly through your account, or using a shared link?
It looks like the file is missing its extension (the three or four characters after the period in the file name; .docx, .jpg, .xlsx, etc.). Did you or someone else have renamed it, by any chance?
That extension is what systems (your operating system, Dropbox, etc.) use to determine what application should be used to open or preview a file. Without the extensions, those systems have no idea what kind if file it is.
If you add the extension back, you should be able to preview the file. Can you give it a go?
