How to use Multi-thread Engine in CrossFTP to Turbo the Transfer Speed

When there are lots of data to be transferred, it is critical to choose a powerful engine to help turbo your transfer speed and save your time. CrossFTP Pro/Enterprise provides extremely powerful multi-thread engine and multi-part upload/download support to turbo your transfer speed.

To turn on the multi-thread transfer engine, do one of the following:

• Option 1: go Tools -> Global Options -> General -> Concurrent Transfers (see Fig. 1).

•  Option 2: after transfer starts, change the thread number at the bottom right side of the status bar (see Fig. 2).

CrossFTP supports up to 100x thread number to maximize your transfer speed, especially when you have lots of files that single transfer thread cannot fully utilize the network bandwidth.

To improve transfer speed and reliability on large files, you can  utilize CrossFTP Pro/Enterprise's multi-part upload and download function. This helps to divide your large file into smaller segments to enable the concurrent transfers and improve the transfer reliability.

To enable multi-part download, go Tools -> Global Options -> Transfer -> Enable Multi-Part download (see Fig. 3).

Multi-part upload needs server side support. Currently most cloud storage provider supports this feature. To enable multi-part upload, go Tools -> Global Options -> S3/Glacier/AZure -> Enable MultiUpload (see Fig. 4).
