I want to work on my local xampp files everywhere
Dropbox is great for that
Lifehacker explains how to create a connection between a non-dropbox folder to your dropbox folder
1. open command prompt with admin permissions
2. run this command after changing the folder names:
ln -s /path/to/desired-folder path/to/dropbox-folder
mklink /D "C:\Users\Nur\Dropbox\xampp_pc" "C:\Dev\xampp\htdocs"
mklink /D "(path to a new folder inside your dropbox)" "(path to the folder you want to sync - htdocs for me)"
