Sync Manager way of syncronize

Hello, now with the new Sync Manager does it do a real syncronization between pc collection and usd drive ? for example if I remove tracks from crate1 and add new tracks to crate1 on PC then the crate1 on USB will be exactly a copy synched by sync manager ? will the removed tracks phisically removed on the USB tracks too ? before the 1.5 engine prime version in order to not have problems with red missed tracks and so on I used to format the usb drive and re-copy all the crates in the USB every time for a new dj sets. Now this can be avoided and syncronize only the changes with sync manager ? I use mcx8000 controller.
