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 , 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, an FTP client, and a find and replace feature using regular expressions. Another feature is "File Difference" view. It shows three windows at a time. Two windows show the contents of the files being compared in editable form, while a third shows the differences between them. This allows manual resolution of source file conflicts, such as detected by SVN.

PSPad interface is based on the MDI with tabs for editing multiple files and better open document manipulation.

The software is packaged ready-to-run, so that no installer needs to be run, and it is semi-portable.
