Homework #5

Design and implement a client/server program that allows a user to retrieve text files from a remote server. You have to implement both the client and the server portion. The requirements are:

• The user should be able specify the full path of the file that he/she wants. For example, if I want to retrieve file "C:\abc.txt" from the server I would type in "C:\abc.txt".
• The user should also be able to specify where he/she wants to put the file locally. For example, if I want to save it to "C:\mike" they should type in "C:\mike".
• If remote file does not exsit, the user should be alerted to this fact and the operation canceled.
• If local directory does not exsit, the user should be give the chance to either create it or cancel the operation.
• If the remote file does exsit, the server should send the user the contents of the file and then close the connection to the client.
• The server should be able to handle multiple concurrent users at once. (hint: multithreaded!!)
• Once the client gets the file from the server, it should save it to the location specified and in the file name that is the same as the original file.
• Once the file transfer is complete, the user should be able to initiate another file transfer.
