List All files on Google drive 5


Please Share



google drive I recently ran across a question on Stack overflow. The question was quite simple how to retrieve the folder values of from Google drive and display them in a directory list using C# and the Google .Net client library.

I have used a PageStreamer in the ListAll method in the event that there are more then 1000 files in the directory this will ensure that we get them all back. PageStreaming is much easier then having to deal with the nextPageToken yourself.

After we have all of the results then PrettyPrint is running recursively to request all of the files from within any directories.

Conclusion

By using PageStreamer you can retrieve all of the rows for your request rather then having to worry about the nextPageToken yourself.

Note: I am not responsible for the usage of your quota if you print everything 🙂

    Hi Linda,
    Thanks for all your examples and explanations. It helped me a lot.

    I have a question.
    I have up to 3000 files on my Drive (service account).

    I have to show some kind of Explorer with the files and folders.
    What would you recommend?
    Read all files at startup and populate the explorer with the result. or
    Build the explorer on demand from root. Which could result in more request.

    NB.
    Do I need to build an Exponential Backoff, when using the “PageStreamer”?

    Thx

      The client library has built in support for back-off. You shouldn’t need to worry about it, we have it taken care of.

      Explorer with the files and folders.

      There is a few things you need to consider with this. The first being memory. Whatever you return there needs to be enough memory in your system to hold the object. Currently you only have 3000 files which shouldnt be a problem just requesting them all in the start and using them as you go. If you start to get more files and things begin to slow down you may have to revisit it.

    Hello,
    I want to list files which are owned by that particular user only, not shared with user. What scope I have to set?
