We are having issue uploading files more than 3GB using Chilkat FTP Library. Is there a max limit? How can we increase the limit?
There is no max limit in Chilkat for file sizes in uploading or downloading. In the cases where a file is gigantic, it's not unusual (especially for FTP), for an upload or download to fail simply because it takes a long time and networks cannot be assumed to be perfect. The solution is likely to have restart/resume functionality baked into your application for such cases, and Chilkat FTP2 provides that functionality. (See the online reference documentation. I believe the property you want to see is named RestartNext.)
