When Options|Word Wrap is on, EditPad will break up long lines to they fit within the width of the EditPad window or are no longer than a certain number of characters. This wrapping is dynamic. It is not saved into the file. Therefore, the file will look different if you change the word wrap settings or open it in another application.
Use Convert|Wrapping -> Line Breaks if you want to solidify a text in its wrapped state. This will convert all soft line breaks introduced by the wrapping into hard line breaks as if you had pressed Enter at each position where a long line is wrapped.
You will also be asked if you want to align the text at the left side only, or if you want to align it at both sides. If you choose to align to the left side only, only line breaks will be inserted, as explained above. If you choose to align to both sides, EditPad Pro will also inserts spaces into each line, so that each line has the same number of characters. The spaces will be distributed evenly across each line. They will be inserted next to spaces already present on the original line. When the file is viewed with a fixed-width font such as Courier New, both the left and the right side of the text will be perfectly aligned.
This function will also turn off word wrap.
If you want to limit the maximum length of each line in the file, you can first set the maximum line length by using the drop-down menu of the word wrap button on the toolbar. Then use Convert|Wrapping->Line Breaks.
You should use Convert|Wrapping -> Lines when you have finished editing a file that will be used by an application or system that does not support word wrapping, or does not support lines longer than a certain number of character. For example, when preparing a message to be posted to a Usenet newsgroup or a message to be sent via email, you should set word wrap to 72 characters and then use Convert|Wrapping -> Lines. There are still a lot of newsreaders and email clients in use that cannot word wrap messages.
