A few years back we released a blog post on how to add a download counter to your Google Drive download links. Part of that post focused on how to share your documents via Google Drive and create a direct download link. Since then we have had many people ask us about the direct download link and the features.
About a year ago, and again just a few months ago, Google Drive made some changes to the way they handle sharing files. There are some people that use Google Drive as a gateway to larger files for their clients like we do , or sometimes you just want an easy way to send someone a file.
They click on the Google Drive link and are greeted with this image to the right. First off, from a business stand point, it is very unprofessional when your customers have to be redirected from your page to Google Drive. It is even worse when the file the customer is downloading is not even downloaded right away, instead it is first previewed by Google Drive. This causes extra confusion and an extra step to obtain that the customers need to figure out just to obtain their file. If I send a customer a link to their product, I expect that when they click on that link that the file will be downloaded, not previewed.
Second, from a personal stand point, being able to send a file and not have to worry about if the receiver can figure out how to download it is a major plus. There are many reasons why creating a direct link to a file is useful, and luckily there is an easy way to do this.
How to create a download link with Google Drive. First off, Google Drive does not allow the user to create a direct download link natively. You will need to alter the URL of your shared file to enable direct download. There are two methods of creating a direct download link; with a third-party application or by yourself.
To create a direct download link follow the steps below. First is the steps to upload and share a file via Google Drive, which always has to be done before you can create a direct download link.
How to Alter the URL manually. When you have your Google Drive Sharable Link copied you will need to paste the link somewhere so you can edit it. I suggest Notepad as it will be easy to see and edit without creating a clickable link.
Your Sharable URL should look something like this:. First, you will need to look at the ID number of the file. In the example above, the ID number is in red:. How this works is by telling Google, via a URL, what to do with the file instead of previewing it. Now when your customer or family member clicks on the link they will be directed to the file itself and not Google Drive default user interface.
This method does have drawbacks. You should also go through this step if using a private window solved your problem. I am going to show you how to clear data in Chrome. You often have to instruct users to go to the File menu and then click Download As to download the file. This is very frustrating when you email or IM the Google Drive file link. The most common response from a user with whom you have shared a download file link is an email from Google Drive asking you to change the sharing settings.
Until then you would have to be content with this little force download URL hack. To make Google Drive document downloadable you will have to know two things 1. The file code or id, which is a 44 character alphanumeric value in the shared URL that uniquely identifies that file. The desired file format. Also, do you know if there is any problem about sending multiple requests do download a file on Drive? Yes, your WebClient needs to have the same cookies that it receives from the download page before proceeding to the "Download Anyway" link.
I've posted the link of PatchDownloadManager. You can't use PatchDownloadManager in your code because it has some dependencies here and there but you can take a look at it to see how I've implemented the mentioned technique in order to receive progress callbacks.
Please be aware that PatchDownloadManager runs on a separate thread in my solution. This can be achieved by changing this line as follows: resultText. Hi yasirkula. It downloads and patches some files at start and fetches version info, after it has patched like 15 files or so I start to get a WebException, error. Something with cookies? I need to patch around 3k files for a game. I don't think it is related to the files not being shared publicly, in that case CookieAwareWebClient would simply download an error page, not throw an exception.
Maybe the exception's details hold some useful debugging information? I see nothing out of ordinary here. Googling "google drive forbidden" yields some hits, one of which is excessive bandwidth usage. I can't really tell if this is a bandwidth issue but I don't I will be able to debug this issue any further. Most likely it is the excessive bandwith usage indeed. I will continue by making a custom script and uploading the files to a web server of my own. Thanks for the help! I am trying to download a pdf, the download is working but the file is actually corrputed.
If you are downloading from Drive, make sure that the file is public. Probably it will consist of an HTML source code of an error page. I seem to be experiencing some issues.
GetFolderPath Environment. Desktop ; FileDownloader. It also comes up with these two Exceptions in the console: Exception thrown: 'System. UnauthorizedAccessException' in mscorlib. WebException' in System. Combine Environment. Desktop , "text. Thanks for the fast reply! FDEr Updated the code, now it supports asynchronous downloads as well as progress callback for these asynchronous downloads. I just implemented this into my project. Although it comes up with an error regarding the sender, e part of the line when calling it.
TotalBytesToReceive ; fileDownloader. WriteLine "Download completed" ;. I've copied the example code directly from Visual Studio after testing it.
What does the error message say? Hi, Thanks for the code, very useful. I just encountered a problem - after downloading 4 small files on a queue using 4 FileDownloader, if I repeat the download queue a few times, I'm getting temp banned from google drive.
WebResponse GetWebResponse is returning a user-unhandled web exception from the server: "forbidden". Just me? Is there any walkaround about this? I haven't encountered this issue myself but I don't think we can implement a workaround for this. Does using a single FileDownloader to download those 4 files one after another change the outcome? If it doesn't, the only possible solution for this issue is to listen to forbidden response and try again every X minutes.
I saw there was a e2. ProgressPercentage was a variable, although it was only returning 0. It returned 0 for a couple seconds, went to , then back to 0 for the rest of the dowload. Also, e2. TotalBytesToReceive always returns WriteLine e2. ToString ; Sorry for the questions. Yes, unfortunately Drive doesn't provide Content-Length in the header of the download request, so WebClient isn't aware of the filesize until the download is completed.
Googling "drive download header Content-Length" yields this entry , you may try giving it a shot to determine the total file size. Can I reference the python script from my c file and return the int? Do you know how to do that? But thank you so much for this! ToString should work out-of-the-box. You are the first person that i have found that has a working solutions for everything! That's all the questions from me, thanks again. Quota shouldn't affect the owner of the file, thus you can continue accessing the file when logged in to Drive with your account.
Try opening the file in an incognito browser tab, I'm guessing that it won't work. This script doesn't copy the file to another Drive account while downloading it. It attempts to download the file from the provided URL and if Drive presents the "File too large for virus scan" page, the script simulates clicking the "Download anyway" button, hence downloading the file no matter its size.
But when the Drive quota is reached, I'm afraid this script can't bypass that quota error. I can't see any possible reasons for this in the source code. I might be missing something but I just can't see it. That fixed it for me, thanks BigDaffa. Your code was exactly the thing I was looking for and it works perfectly! Well done!! NET experience. You can try using the online C to VB.
NET converters, though. Especially if it's about big sized files, we would love to see an auto-resume download functionality in this one! What do you think? Yes, it would be a useful feature but I'm not planning to implement it myself at the moment.
But thanks for the suggestion! If you are trying to learn how to create an interactable button with. Then, you should be able to implement this feature very quickly. How could i check if the download is done? You can execute your code inside the DownloadFileCompleted callback which is called after the download is done.
Sorry for bothering. I tried to put my direct dowload link here. What should happen, or where it's dowloading. Maybe didnt put in right place. Since the file is too large, you should show the progress somewhere in your UI, inside the DownloadProgressChanged callback.
Progress in [0,1] range is: double e. Figure out how to make all work. Now, when I am downloading I have webresponse error On russion website I found that the website undertand that I am using program, but not browser and blocking me. Here is the solution, but I don't undertand hot to apply it to your code.
Drive files have a bandwidth limit the exact limit is unknown, though.
