WinSpeedUp is already available in 6 languages: English, German, Italian, French, Czech and Russian. Your own translation can be done very easily. In the directory of WinSpeedUp, which is usually located in C:\Program Files\WinSpeedUp, there is the subfolder "Lang". Every translation consists of two files: a .ico file with a flag that represents the language and a .ini file, which contains the actual translation. To translate WinSpeedUp into another language, just make a copy of any .ini file (e.g. eng.ini to choose English as a base) and edit the file. Any text that appears in WinSpeedUp is contained in this file. Since some of the text are changed during the execution of the program, they include variables: %1, %2, etc. These variables must be preserved in translation, but they can arbitrarily change position in the text.
WinLube can be translated in the same way. You will find the language files in the subfolder "Language" of the WinLube directory (usually C:\Program Files\WinLube). There are no .ico files needed for WinLube. The .ini files are structured the same way as those for WinSpeedUp as described above.
You are welcome to send your translation to email@example.com. As a reward for the effort you will receive a free license key for one of the programs.
