I need a way to protect files

[maxpower]

Im making a game for my visual basic class at school, and i need a way to protect the files from being modified by classmates. How can i do this.

[Cobo]

You mean like source files or game files? With game files I guess you could go quake style and create a 'pak' file with compressed data.

[Eiii]

Sort of along the lines of cobo's suggestion, you could zip it and then change the extension to .jpg or something, and unzip it when you need to use it again.

i mean game files. i dont think that would work efficient enough, moment someone finds out how i did it boom they pretty much got the files.

password protected zip file or usb thumb drive

New ViciouZ brand super protection!

1. Add to encrypted RAR file.
2. Put the RAR file in an encrypted ZIP file.
3. Rename the ZIP file to .DLL, or a format likely to be that size.
4. Put it in a hidden folder in the deepest darkest subdirectory you can find, and make it sound important, e.g. windlls. Mask it with a load of DLLs.

There.

how am i suppose to read it then, i need to encrypt so they cant modify them for the game. like i was to hand it out for people to play, i dont want them changing the images and stuff.

or...

Install ANY of Sony's latest games and hide it in their root kit hidden folder

Or use the eR00tkit.


Maybe just put it in a Read Only Folder?
hmmm

Create a folder somewhere
right click on the folder - select properties
click on security
uncheck the box that says "inherit properties from parent folder"
Now add the user names that you want access to that folder.

^^That seems like it might be a good way to go.

Read only wouldnt work, its going to say this file is read only so no. I'm not sure if you guys understand what im trying to do. Im trying to protect the game images, like protecting the player skins and stuff for paintball. I need a way to catch people that edit them or like check md5 checksums of the files.

[ViciouZ]

Look in the DP source and copy the md5sum check?

[maxpower]

Thats in C++, i said im doing it in visual basic.

Does anyone here remember that day that MS added "lock folder" as an option to XP via an update, yet immediately removed it after everyone forgot passwords to very important files?

Anyway, Max, are you protecting game data or source?  If you're protecting game data, encrypt it, otherwise, keep it on a flash drive and never let your classmates have access to it.  Unfortunately if they *could* get it, they almost certainly can if they want it bad enough.

And what did I suggest earlier?

I was asking if anyone remember the botched attempt to launch "Microsoft Private Folder 1.0" .. not suggesting he use it or any form of it, especially a pirated copy.

Now THAT would be a good way to get people to register.  "Your demo has expired.  If you ever want to see your files again, send $50 to...."
