I want to be able to set custom metadata on a file in dropbox. Ideally a string of at least 32 bytes for each file. I've looked through the core API docs but I haven't seen a way.
However I'm new to Dropbox so maybe I missed something or there is another way?
Thanks!
There isn't any way to set additional metadata on the file for your app. You could use the Datastore API (https://www.dropbox.com/developers/datastore) to store the string and the associated file path.

I have image upload in my system. I am struggling to understand what is the logic of serving images.
If I upload directly to wwwroot, the files will be accessible to everyone, which is not what I want.
I understand I could save the file contents in the database as base64 but those can be big files, and I would like them on the server in files.
I could convert them on the fly when requested. Most probably getting the path to file, then loading it in a memory stream and spitting out the base64. But seems overkill, and not an elegant solution. I use Automapper for most data and I have to write some crazy custom mappers, which I will If there is no other way.
I could create virtual path, which from what I understand maps physical path on server to a url which doesn't seem any different than option 1
I fancy there is a way to spit out a link/url that this user has access to (or at least logged users) that can be passed to the app so it can load it. Is this impossible or unreasonable? Or am I missing something?
What is the correct way of doing in general?
Also, what is a quick way to do it without spending days for setup?
To protect the specific static files, you can try the solutions explained in this official doc.
Solution A: Store static files you want to authorize outside of wwwroot, and call UseStaticFiles to specify a path and other StaticFileOptions after calling UseAuthorization, then set the fallback authorization policy.
Solution B: Store static files you want to authorize outside of wwwroot, and serve it via a controller action method to which authorization is applied and return a FileResult object.
Current Dropbox API searchFileNames() allows the searching of a query / substring, so if I wanted to look for filenames in a folder that were of a specific extension such as ".jpg", that works, but if I combine to look for ".jpg .png" I get nothing returned... as the documentation states 'A file matches only if it contains all the substrings.'
Is there another API that will allow a union of the searched vs the exclusion?
Thanks
No, the Dropbox API doesn't enable you to search for multiple file extensions at once like this, but I'll be sure to pass this along as a feature request.
As a workaround, you can split this into multiple API calls.
I'm using Dropbox V2 APIs (C#) to get files/folders from Dropbox account. I am able to fetch particular file/folder by using its specific path. I wanted to know whether there is any way I can fetch file/folder by using ID?
This depends on exactly which operation(s) you're referring to. For example, downloading files and getting metadata for files or folders support specifying file IDs:
https://www.dropbox.com/developers/documentation/http/documentation#files-download
https://www.dropbox.com/developers/documentation/http/documentation#files-get_metadata
You would specify the path as a string like "id:a4ayc_80_OEAAAAAAAAAYa".
Searching and listing folders currently do not support this though:
https://www.dropbox.com/developers/documentation/http/documentation#files-list_folder
https://www.dropbox.com/developers/documentation/http/documentation#files-search
The same applies to the corresponding methods in the SDKs.
Edit: list_folder and search now do support file IDs.
I am using the REST API for OneDrive. I have a name of a file in the users storage. I want to obtain the properties for this file. According the documentation file's properties can be retrieved
if you have the file ID.(http://msdn.microsoft.com/en-us/library/dn659731.aspx) So I need the file ID and the only way I see to obtain it is to search the whole storage which is really unnecessary.
Is there a way to find properties of a file(with a known name) with a single request to the service?
Ideally the API would support access by path which would do what you require (assuming you have the full path and not just the name). Unfortunately, to my knowledge that isn't supported.
There is a heavy handed approach that may work for you though - you can use the search capabilities of the API to find files with the name you specify:
GET /[userid]/skydrive/search?q=MyVideo.mp4
The documentation is available at the link below:

We have a system that generates documents using the Google API, we would like the page set-up to default to A4 for all documents we generate. We have set the default as A$ in the Google Doc settings but this doesn't carry through for files created using the API.
Is there something we need to set in the API call to generate the doc?
Thanks in advance,
David
Is there something we need to set in the API call to generate the doc?
Unfortunately it looks like this option isn't supported via the API, either on file creation or on file update. Google Docs/Drive treats page setup as an application setting as opposed to a per-file setting.
Here's the full list of metadata that you can specify about a file: https://developers.google.com/drive/v2/reference/files
