How to make a program that automatically synchronizes

Hey i am hoping to write a program where the program automatically just copy pastes all my dad's documents from D:\office folder. So whenever I plug-in my pen-drive , the program silently copies all documents inside my pen-drive. Also all files should be pasted to a hidden folder in the pen-drive (so it remains private) . Synchronization capability also required ...So 开发者_开发知识库which language should be easy and where to get started ...any idea ??.

Seems to me that some spyin' is about to be goin' on here. :P

I'd recommend C++. Not extremely easy as .Net's tillyvally but fast, framework independent, convenient to manipulate Windows API. You wanna do advanced stealth app, you can't pick the easy way.

Why use the clipboard when you could just use shell commands???

Maybe write an autostart batch file on your pen drive that copies files to/from your flash drive as needed.

I infer you are on Windows. Window has a plethora of functions to manipulate files. A few functions are below.

• CopyFile Copies an existing file to a new file.
• FindFirstFile Searches a directory for a file or subdirectory name that matches a specified name.
• FindFirstFileEx Searches a directory for a file or subdirectory name and attributes that match those that are specified.
• FindNextFile Continues a file search.
• MoveFile Moves an existing file or directory and its children.

On and on. These and many more functions are documented here.

File Management Functions

Copy or move the files to the pen drive.

HTH

I hate to be the person who suggests this (I don't like .NET that much):

Make a C# (or VB if you must) Console app, or Forms app (if you want to get fancy). The .NET framework will make this kind of program VERY easy and it might be fun. Unless you want to increase your proficiency in C/C++, i would suggest NOT doing it in those languages since there is a learning curve and it is a little complex to do some simple things.

"Just paste" or "synchronize"?

For synchronization, unison is a good bet, see http://en.wikipedia.org/wiki/Unison_(file_synchronizer). For "just paste", you could code a call to a batch calling XCOPY from with the Windows Autoplay mechanism.

Sounds like a secret covert operation you're talking about, though...

I think that you will need to do a lot of work to get a less than satisfactory result.

I would suggestion you instead have a look at DropBox, which is free up to 2Gb of storage which automatically synchronizes between all registered computers, plus has a special folder which allows for web access. Very nice.

I would suggest to use Camel framework of Java, there you can easily run service which will for example automatically copy data from your flash disk after plug in, to folder which you specify etc. Good tutorial how to start is here: https://www.youtube.com/watch?v=dmtXkA7FlwA
