How do I search for file on an Android device

Question

I am developing an asp.net app. On the client-side a user may save a file to their local android machine. I need assistance on how to navigate the android machine to find that file and confirm it exists before the user leaves that web page.

I am familiar with Windows, but not android.

Is there a flag that tells me what client OS is being used.

I am proficient in C# but not Java, and looking for a client-side java solution.

You do not have access to the client machine (Android or any other OS). Your web page may initiate a download but the user controls where the file will be saved. In the case of Android devices it is in the 'download' folder.

Is there any way I can check in which folder the file was saved, if the user didn't save it in the 'download' folder?

No. You need to understand that web pages are not allowed access to the client's hard drive. This would break security and allow viruses to be dumped on user systems quite easily.
