I'm able to get all the files from server.
But while downloading getting following exception,

Exception in thread "pool-1-thread-8" org.aarboard.nextcloud.api.exception.NextcloudApiException: com.github.sardine.impl.SardineException: Unexpected response (500 Internal Server Error)

Also tried to download the single file just to check.

Server location : /Photos/Nut.jpg

Console output for the same is as follow,

Can you please try with another file?
Can you see what the nextcloud server is throwing for an exception?

A error 500 is a server side error, which usually indicates that something has gone wrong on serverside

I tried but won't work.

So, I did some changes in code it works but fail to download the bigger size file. like above 40MB cant download.

Your code : in Files.java

			in = sardine.get(path);
			byte[] buffer = new byte[in.available()];
			in.read(buffer);
			File targetFile = new File(downloadirpath);
			OutputStream outStream = new FileOutputStream(targetFile);
			outStream.write(buffer);
			status = true;

Updated code:

		InputStream in = sardine.get(path);
		byte[] buffer = new byte[1024];//new byte[in.available()];
		int bytesRead;
		File targetFile = new File(downloadirpath);
		OutputStream outStream = new FileOutputStream(targetFile);
                while((bytesRead = in.read(buffer)) !=-1){
                        outStream.write(buffer, 0, bytesRead);
                }
                outStream.flush();
                outStream.close();
	        status = true;

Thanks for fixing it.
Your code is now included in the 11.0.2 release
