USB Storage

If you're using only HTML CSS and scripts then you will be fine to work from your USB. These languages are client side.

If you were using PHP for example this method wouldn't work, PHP is a server side language an requires the correct environment including SQL and a apache for example.

In answering you question, you should have no problem using your USB for you current requirements.

It shouldn't be a problem. I would recommend backing it up on your home computer (copy the files but also leave the files on the stick) once in a while in case you lose it.

On a side note, I have a 64Gb thumb that I have linux installed on that I can use on any computer that allows to boot from USB. I use it primarily on a netbook that's slow as beans in molassas when using Windows that it came with, while it seems significantly faster with Linux on the thumb drive.

I have all my dev tools on it and I've been using for many of my Treehouse projects, as well as others. I don't do any graphic design with it; only for coding. I backup all the files regularly and don't keep anything on it that really matters for very long. It's also an encrypted install so if I lose it, yeah it wouldn't be great, but there is nothing too identifying on it for very long since there are no persistent logins for anything -- I have to manually log in to whatever web service I use each session. It takes longer (more typing involved and such) but it's more safe.

I hope this isn't too much info...but, saving files to a USB will not mess anything up. As an EXAMPLE: if you have are downloading a file named html_forms.zip...

1. Download this to your computer.
2. Create a file on your USB and name it html_forms
3. Right click on the downloaded folder. (the computer will ask you where you want the file extracted to)
   
4. Click "browse"
5. Choose the file you created on your USB drive.

The files will be extracted to your USB and they will have the .html and .css file extensions. You can open these files in which ever editor you are using (Sublime, or Notepad++, or whatever you are using on your portable device.
Hope this answers your question.

Thanks for all the help guys. I just want to make sure before i unplugged it to use at other locations that i wouldn't lose the path when i load it later. I was also looking for a Linux program to download to a flash drive for later use but couldn't find anything to work just by googlilng it. I'm just at the HTML part now. it looks like ill have to get a different laptop for the other ones. I have a 8lb 17in goliath now that's a pain to care and just fits in my bag.

The only problem I could forsee would be absloute paths in your links such as

<a href="C:/my_folder/moy_folder/myfile.html"></a>

This would go bad if you switched computers. To prevent this use a relative path like

<!--This assumes myfile.html is in the same directory as the file linking to it -->
<a href="myfile.html"></a>

Thanks Ricky. I'll keep that in mind is i do an absoloute path. I'm looking to to smaller and lighter computers now. Maybe a Mac because i want to do IOS stuff and it looks like thats the only way to do it.
