How to map an ftp share folder to a local drive us

问题:

How do I map an ftp share folder to a local drive using C#? Is there any class library available for this?

I need to achieve the same functionality as NetDrive(http://www.netdrive.net/) offers using FTP ?

Maybe you can leverage someone else's work and get a headstart. The makers of NetDrive for instance offer an SDK - not sure what that requires / costs, however. But it might be worth an inquiry, no?

And maybe, if you combine this approach to define a remote FTP site as a Windows network share, and then use this code in C# to mount a network share as a drive, you might get your job done :-)

It's a very tall order - if you actually want a local drive, e.g. X:\, to access an FTP site, you'd surely need to write a driver. Not an easy task.

If you want it to simply appear in Windows Explorer somewhere - you can use the shell extension as Marco's answer suggests. But don't expect to be able to treat it like a regular drive.

To create a virtual drive or a folder on existing drive and expose remote FTP server contents that way you need a filesystem driver. Or use can use our Callback File System (CBFS) product which lets you write the code in user-mode and includes a pre-created filesystem driver. CBFS includes a sample, SFTPDisk, that does exactly what you need, but with SFTP protocol (SFTP is not FTP but SSH File Transfer Protocol).

Note, that in FTP there's no function to upload a block to the middle of the existing file. This makes some file write operations trickier than with SFTP or local filesystem - you may need to cache the whole file and upload it asynchronously when it's closed by the client.

There's a project in C# to use an FTP folder as virtual drive -> http://amalgam.codeplex.com/ (it uses dokan).

There's a freeware program that does the same thing -> http://www.ferrobackup.com/ftpuse/
