WinSCP cannot do this on its own, you have to code it.

I want to upload part of collection of files every few seconds, wait for sometime and later upload specified number of files.

For eg. upload 30 files out of 1000 files in one go, wait for 5secs and again upload another set of 30 files and so on

Is there any way to automate this using winscp scripts or do we need integrate normal winscp upload script with any of the other languages ?
