a program that you can use on your usb so that you can not enter your usb without a password. or ou cant enter certain maps on you usb flash drive. my englisch is very bad but i thought it is called an encrypter but when i download a encrpyter i could onlyencrypt files to zip etc. so can you make a simple but safe security program for a usb?
It has been asked for many times before, and the simple answer is that if you use a software solution, it can be bypassed, broken or just plain ignored.
The only way to have a truly encrypted USB drive ("password protected") is by using hardware encryption, as with a product like IronKey.
The easiest, partial software solution is to use something like TrueCrypt or FreeOTFE to create an encrypted "partition" on the USB drive (or encrypt the whole drive). However, this is not quite the same as having a "password protected" USB drive, but it is about the closest you can get with a software only solution. Furthermore, the problem with this approach is that you will need administrator privileges to write to the drive.
Your English is fine.
It does the job. Google it. Has a limited but free edition, not open source
Don't really see how this is any different to TrueCrypt or FreeOTFE, except that's limited and not open source, but alright.
i tried on a school com without admin rite and it can decrypt. And it does not need to make a partition
I used the term "partition" loosely. I haven't used TrueCrypt but FreeOTFE certainly doesn't require an actual dedicated disk partition. You can create an encrypted "volume" or container (and decide how big that container should be). If you use FreeOFTE Explorer then you don't need admin rights, the only downside is that you have to manage files through the explorer program, so you can't work with the encrypted volume like a normal drive (i.e. assign it a drive letter), but this is the nature of this type of software.
Anyway, it doesn't really matter, if you're happy with your solution and I'm happy with mine, I guess that means everybody is happy.
Using something like that is basically equivalent to keeping your important files in an encrypted 7-Zip container and moving them out as you need them. You should be sure and wipe disk space if you're concerned about people undeleting in either case.
Sometimes, the impossible can become possible, if you're awesome!
You can actually render a flash drive useless on Windows PCs by formatting it in Mac OS Extended. This way, it can only be used on a Mac. The obvious problem with this is if you don't have a Mac (thankfully I don't have this problem).

My use of Google indicates that I am insane.
As somebody else said on here the other day (I think it was here); "Security by obscurity is no security at all". If someone was determined to get your data it wouldn't take them long to figure out how the drive was formatted. And like you said, you've basically tied your "security" to one operating system.
how many people think when the beautiful colorful surface of the operating system does not show anything then there is nothing here and can not be read.
In fact when it come to data files, text, pictures and similar in generic formats, it does not matter how you format the drive, decent file recovery will recreate the files what ever formating you do.
Recently: colleague of mine, installed windows XP over his ubuntu computer, this destroyed all existing /home /root and what ever partitions and data was 'lost'.
No problem! We run testdisk over it just to see what is left of the linux partitions, then used very basic and trivial recuva tool and restored 100% of the data he was looking for, well it was all jpg so this was easy I admit.
