When I'm programming, I often need to open the files of different program-languages. Reading for convenient, I have no choice but to open various Software Develpment Kits. But openning too many SDKs will decrease available resources of system and influence the performance of computer seriously.So in order to solve this question, I develop this software. At present, SuperEditor V2.0 are supported 14 syntax rules such as TXT files, ASP, BASIC, C\C++, FORTRAN, HTML, JAVA, LISP, INSTALLSHIELD, PASCAL, PERL, PHP, PYTHON, SQL, etc. If the files are supported by one of these program-languages, it will highlight the keywords in various colors. It offers an openning method like the explorer and also offers document previewing, read only, full screen etc. It can manage all the openned windows. then manage the windows will be easy. If you think the software take convenience to you, you can think over if you want to register it. It is very cheap, only costs $19.95.
