I'm doing a basic e-commerce site and I have my files backed up on a thumb drive, doing coding myself, using notepad++.
I need to do some changes before uploading to server,but when I do, it saves the update as a copy, and I'm worried that a copy may break the links. Am I correct in being worried? I have made mistakes that have costs me hours and hours in tracking down, so I was hoping someone might give me some suggestions. Thank you!
