There are a few basic DONT'S when creating/naming files and directories on a PC.

1. DON'T use any characters except A-Z a-z 0-9 _-
2. DON'T use spaces in a file name, if you need a space use the underscore "_" character instead.
3. The use of the following characters can cause serious problems since they can also be control codes and can be used by programmers to issue instructions to the CPU.

Here are a few basic DO'S when creating/naming files and directories on a PC.

1. Give your files/directories meaningful names.
2. Bearing the above in mind, try to keep your filenames succinct and as short as possible.
3. If you intend to publish your files on the web it is a good idea to be consistent in the way that you type your filenames. Windows doesn't care about whether you use upper or lower case letters, or where you place them. However most web-servers run under Linux or Unix, not Windows. Both Linux and Unix are case sensitive!
So, if you have a file called "My_File.PZ3" and your web page has a link to "my_file.pz3" chances are that your user's browser is going to show them a "File Not Found" message......
