PSPad

PSPad editor is a freeware text editor and source editor intended for use by programmers. First released in 2001, this software is produced by a single Czech developer, Jan Fiala, for the Windows platform.

PSPad has many software development-oriented features, such as syntax highlighting and hex editing, and is designed as a universal GUI for editing many languages including PHP, Perl, HTML, and Java. It integrates the use of many project formats for handling and saving multiple files. PSPad also edits UTF-8 encoded texts. Other features include autocompletion, tabs, FTP client and find/replace using regular expressions. One of PSPad bright features is "File Difference" view. It shows three windows at a time. One window shows difference while two others show files itself. And these files can be edited. This is especially useful to manually resolve source file conflicts, for example detected by SVN.
