In this blog, I show you how create a zip file of one large file, split it in smaller zip files parts and upload one by one file on FTP account.
The attached project is a Visual Studio solution file that use a third party dll to connect to the FTP and upload the file. The code also check the file size of both side files (local and uploaded file on FTP) and store new file in separate folder on FTP.
The third part DLL is IONIC.ZIP.
You need to modify the solution file and provide your FTP details and make sure you have " write " permissions on the FTP account and the folders.
