I want to synchronize the folder one time in day and not look for changes in it constantly

Sorry, but I do not understand you.
WinSCP does not do "look for changes constantly", unless you yourself scheduled execution of some WinSCP script.

How do you want to limit the requests? Do you want to prematurely stop synchronization before it completes, so that the number of S3 requests does not exceed a certain limit?

How do you want to limit it?

For two days in the local store about 60 files. Requests for Amazon: s3 put - 1959, s3 gets - 294.
I want to reduce the number of requests put and get.

Is it possible to set the synchronization start time?

You can schedule a synchronization script using Windows Scheduler, if that's what you mean.

Is it possible to limit the number of requests for synchronization with Amazon s3?
