c# - Is it a bad idea to copy project folders for backup? Add existing items instead? -

-

i'm learning c# (self-teaching first real programming language other vba).

consistently, text book asks me create new project , add bunch of existing items old project when don't want mess existing project. seems way of creating backup. never said not copy folders i've been doing , works fine.

the ide doesn't allow save whole project new name (i.e. save as: "backup of projectname") instead close ide , copy folder. it's been great time saver rather following laborious instructions fear i'm teaching myself bad habit. please tell me fears unfounded.

in case else comes along seeking answers - note question has been answered via discussion in comments.

it sounds practice won't blow there's better way: "version control system" or "vcs". i'm going have little research , pick 1 before semi-bad habit gets ingrained.

thanks @xantos , @daniellane!
