I have problem while downloading the file using .net dropbox API. The file contains special charaters any suggestion how to download a file with special charaters using Dropbox API. While trying to download its saying "path/not_found/...".
Special Charecters like - ( . ) exp : at - (some time . GSK) name.pdf
Is that the exact code you're running? I just tried it with v4.9.3 of the .NET SDK, and it worked fine for me.
A 'malformed_path' error indicates that the supplied path isn't in a valid format. The path "/Test/Tiny, Tone - (In DropBox) sample.pdf" is valid though, which is why I'm wondering if this code isn't exactly the same as what's running in your app.
