The big downsides are cost and flexibility. You’ll get full control of the server and its setup, including how much storage space you provision, how many users you create, and more. There are two main options for setting up an FTP server for your business.įirst, you can set up and host the server yourself. The costs, technical aspects, and functionality all play a part in deciding how best to meet your requirements. A basic understanding of server setup can be helpful whether you are hosting your own server or using a hosted FTP service. If (not overwrite and os.path.isfile(fullpath)):įtp.retrbinary('RETR ' file, f.A secure FTP server is an ideal resource for file transfer.

I've placed it on Gist here Īnd pasted it below in case i ever take the gist offline.įtp = ftplib.FTP(mysite, username, password)ĭownload_ftp_tree(ftp, remote_dir, local_dir) I ended up writing my own solution that works very well for me. This is a very old question, but I had a similar need that i wanted to satisfy in a very general manner. With open(os.path.join(destination,file),"wb") as f: #possibly need a permission exception catch: #invalid entry (ensure input form: "/dir/folder/something/") #path should be the abs path to the root FOLDER of the file tree to download #path
