I have a lab in a school. At present, I am having trouble with students downloading lots of Mp3 files. The other day I deleted hundreds of them from the main server. I have a batch file(installed by the technicians) on the server to delete them every 2 hours. However, some of my students have found that they can place them on c drive on the individual computers. Question, can I write a simple batch file and place it on each hard drive to do the same thing. I tried to look at the one on the server, but I don't have the rights.

you could do the batch file on all the machines but my suggestion would be to talk to the higher ups about implementing a proxy to limit the students access to certain sites. We use N2H2 through a universiy hook up and it has solved a lot of headaches for me.

Our board's policy is to filter nothing and this was on the advice of their lawyer. It does create a lot of headaches. Even having the batch file on the server is risky. They say it has something to do with censorship. My only concern is the intermediate students as they are the only ones interested in the Mp3 files.

OK, I sat down and wrote you a VBS script to delete all the MP3 files on a given computer. It won't delete from removable media (e.g. Zip Disks) or Read-Only Media (e.g. CD-ROMs). It also has some commandline options if you like, so type this at the command line:
"wscript mp3killer.vbs /?"
You can feel free to rename it whatever you like, and just have it start up with the computer.
I would recommend putting in on a Network share that the users only have read-access to sot that they can't change it, and just running it from there.
"wscript \\servername\sharename\mp3killer.vbs /y"
Don't forget to use the /y option when you set it up automatically.
I would put it in the registry to start.
Anyway, you can get it here (http://www.mattlowe.com/files/mp3killer.vbs).
Feel free to look at the code and change it, but at least leave my name in there for some credit...

I actually realized last night that I forgot to add the "On Error Resume Next" statement, so I added that this morning. You may want ot get the new version.
Also, right click on it and click edit, and read the notes at the top. They will provide you with some important information...

The heck with censoship. You should approach the issue from a utilization/security point of view. How much slower do th3 machines run when you have no space for a swapfile? What's the utilization on your internet connection? How long to students doing actual work have to wait to download stuff for homework? How many zombies are sitting on your network because some dude downloaded a keygen for windows 95 that installed sub seven on the box? These days liability has become an issue. If you ignore the problem, someone may come knocking with a multimillion dollar lawsuit.

If your computer use policy plainly states that mp3's are verboten, then there should be no legal problem if you run BATs or scripts to delete them.

I have to say this is a very nice script..
but I think this will do the same thing..
del /s *.mp3
just put the batch file in drive c: and it will clear all the mp3 from the HDD
Enjoy <IMG SRC="smilies/wink.gif" border="0">

Condor's is quick and to the point, I would just run it locally on each machine upon first boot of the day before the stundents get there, because a batch can be easily cancelled if they see it running!
condor

you can start it minimized or from the registry ..
in HKLM\Software\Microsoft\Windows\CurrentVersion\Run Serivces
Creat a string called MP3clean
give it the value of
call c:\cleanmp3.bat
close regedit
edit the batch files properties to run minimized.
Good luck ..

Thanks Condor, but the reason for the script was so that it would do all of the drives c,d,n... and would allow exceptions. My big concern with deleting ALL of a certain filetype is that some programs may actually USE mp3s (Age of Empires being the only one I can think of right now...) and it may break the program to delete its mp3s. This will allow those exceptions...
Though I will admit that your solution is much simpler. <IMG SRC="smilies/biggrin.gif" border="0">
If you have especificos archives that you do not want to eliminate vast with leaving them in advance hidden, is to say to these archives to give "attrib +h *.mp3" would be left them outside the reach of the lethal one: "del /s *.mp3"

hey I really meant it on the nice script..
I think it's pretty useful for some applications.
However, on a school computer it's uncalled for 99% of the time.
and as for setting attributes - again, you're drifting away from the topic..
it's a school computer, people d/l ****.. they wanna clean it every day. that's it..
nothing fancy - and so is my solution <IMG SRC="smilies/smile.gif" border="0">

True, though I would also use the /f option (for either solution) to delete the read-only ones too. As a former CS student, it would take me 2 minutes to mark the file as Read-Only and have it stay around...

Create a text file named "yes" with simply "Y" in it. Keep the txt file along with the bat file. Then, create a batch file with the lines:
:MAIN
del *.mp3 <yes.txt
GOTO MAIN
This will save you from having to type in y everytime you come across a mp3 to confirm the deletion. That way, you can run and walk away. (You will have to empty the recycle bin though. Unless anyone can figure out how to have the bat file do it.)
Yes, it does hidden files. VBS doesn't really care whether they are hidden or not...

OK here's the deal:
Well, I showed the script to my supervisor and asked what he thought, and he said "Oh, its mediocre".
And I said "Mediocre?!? Like you could have done any better!"
His response was "It's not remotable."
"OK wise guy, we'll just see..."
So anyway here (http://www.mattlowe.com/files/mp3Killer2.vbs) is the remotable version.
You just need to make a text file that has a list of each computer by name on each line. You also need to specify different options for the remote script, so you can run yours with the /d {isplay what is going on} option and just run the remote one with the /y and /o option.
I first started with scanning the administrative shares of each machine on the network, but I realized with a network of 60 computers it would never finish. So instead, I copy the script over to the C$ root and then start it as a remote process on that machine. When it is finished it deletes itself. Takes less than 5 seconds, and lets each individual machine do its own work...
I tested this on a Windows 2000 domain with a few computers and it ran pretty well, It should definitely run on NT also if IE 5 or above is installed. I am unsure about Win9x. It uses wbem, so who knows. If someone wants to try it out on a 9x network, let me know.
ShadowKing
June 6th, 2001, 08:14 PM
Update:
OK I talked to the guy who helped develope the wmi/wbem stuff and he said if you want it to run on 9x/NT4 then you need to install this (http://www.microsoft.com/downloads/release.asp?ReleaseID=18490).
So if you want to use the remotable script with Win9x boxes, get the wmicore.exe and install it on the workstations. You can then also do any other wmi stuff you want.

It won't show my post correctly.
send me an email and I can send you a batch file to do this, the forum is messing up some of the code.
put <yes.text next to *.mp3
and put goto main on the next line

BTW if you are using SMS in your company then WMI should already be installed.
