Using the Core BulkDocumentUploader sample add-in

From the Main method in Program.cs, the RecurseActions method calls the Run method in OneDriveMapper.cs. The Run method gets the location of the file to upload from SharePointSites.csv, and then calls the IterateCollection method.The SharePointSite.csv file lists a file to upload and the document library to upload that file to. The IterateCollection method then does the following to upload the file to the document library:

• Gets the file to upload.
• Ensures that the user has permissions to add items.
• Creates the HttpWebRequest object with the authentication cookie, the REST string request to upload the document, and the HTTP request action method.
• Performs the file upload.

• With Virto SharePoint Bulk File Upload, you can quickly upload multiple files to your SharePoint list or document library by simply selecting the files and clicking the upload button. No need for the redundant task of the same action repeatedly for each of files with SharePoint Upload Web Part from Virto.
• Upload files with drag and drop. Virto SharePoint Bulk File Upload supports drag and drop mode. Just drag files to the upload window and start the process.
• Upload large files (up to 2GB) to your SharePoint. No more rejections of large files adding to your collection! Using Virto SharePoint Bulk File Upload, you can now upload large files up to 2GB.
