I need to sync files according to the time change without deleting the files (if a file is missing or the entire folder is empty).
for example: I have 10 files on the server and 1 file with the same name as on the server is created on the new device (PC not server) and I need to synchronize this files, so that there are 10 files on both the server and the PC.
If you use copy, the source gets copied to the destination.
If you use sync, the source gets copied to the destination and anything on the destination not on the source is deleted.
If you sync 10 files from the source, the destination will have 10 files on it regardless of what it looked like before.
