Using it, you can easily connect to a remote server and download files to your local machine. It allows to send http post request and get request in php as well.
Executing a basic curl request will simply return the data to the output stream. But we don't want that. Instead, we must assign it to a php variable, which we can write it to the disk. But there is a problem with this method. Below we will see the right way to download remote files with curl. I need to download file i. Based on the mimetype i have to seperate them in different folders. You'll easily exceed memory limits, given the entire data has to be read into the memory before writing it to disk.

Most people would prefer a progress bar while downloading. So i just wrote the simplest way to do that.
This might not be the answer but it meets the requirement of Stackoverflow. That is to help someone. This is just as simple as the other answer if you just leave out the progress bar. Also the question doesn't ask for the simplest way, just a simple way.
Jessedegans There is already an answer that shows how to simply download without a progressbar. Thats why I wrote an answer that helps with asynchronous download and progressbar implementation — Abdul Saleem. This answer is good, probably better and more detailed than the one with more upvotes. It's almost obvious that one needs a progress indicator while downloading a file. The asynchronous functionality is a bonus. I was looking for such an implementation.

Generally it's not a good idea to post a low-quality answer to an existing and old question that already has highly upvoted answers. I found my answer from seanb's comment, but truly I prefer this "low-quality" answer over the others.
It's complete using statement , concise and easy to understand. Being an old question is irrelevant, IMHO. But it think the answer with Using is much better, because, i think the WebClient should be disposed after used. Putting it inside using ensures that it is disposed. It has nothing to do with dispose in this code example The using statement here just show the namespace to use, no that WebClient is use into using to be dispose Complete class to download a file while printing status to console.

Support for method "libcurl" is optional on Windows: use capabilities "libcurl" to see if it is supported on your build. There is support for simultaneous downloads, so url and destfile can be character vectors of the same length greater than one but the method has to be specified explicitly and not via "auto".
For methods "wget" and "curl" a system call is made to the tool given by method , and the respective program must be installed on your system and be in the search path for executables. They will block all other activity on the R process until they complete: this may make a GUI unresponsive. It is used by available. The "wininet" method supports some redirections but not all. For method "libcurl" , messages will quote the endpoint of redirections.
