Deleting files on a remote computer

Can I connect to a remote computer and delete files from it? If not, are there other approaches that can solve this problem?

One thought is that I can create a service that runs on each machine, implement a method that deletes local files, and then send commands to that service.

If you can achieve this via a standard network path, then this is the easiest way. \\machinename\c$\

... You must be an administrator on the machine to reach this path. This works with System.IO objects (File, Directory, etc.).

If you cannot get to the network share, you can create a batch file for remote execution.

So remove.bat

c:\
cd \Windows\system32\example\
rm *

and use psexec to copy the bat to the remote machine and execute it there.



psexec \\example-computer -f -c remove.bat

After the exit psexec bit is complete on the remote computer.

psexec uses netbios, so you should be able to initiate a netbios session on the remote machine.

If it's a computer on your local network or VPN, you can use a UNC path, but you need to know each username and password. You will need to use the WNetUseConnection Win32 API from C # to connect to your computer. Once connected, you can delete files in the usual way. Just provide the full UNC path to the file \\machine\c$\file.txt

.

If the machine is on a network rather than a local network or VPN, WCF sounds like you are looking for. You can create a service contract with a file delete operation. There is a huge introduction to WCF Services here .
