ReactOS is a free and open source operating system written from scratch. It's design is based on Windows in the same way Linux is based on Unix, however ReactOS is not linux. ReactOS looks and feels like Windows, is able to your run Windows software and your Windows drivers, and is familiar for Windows users.
Development began in 1996, as a Windows 95 clone project, and was continued as ReactOS in 1998, with the incremental addition of features of later Windows versions.
As of July 2018, ReactOS is considered alpha software, feature-incomplete but with many Windows applications already working (e.g. Adobe Reader 6.0, OpenOffice, etc) and therefore recommended by the developers only for evaluation and testing purposes.
ReactOS is released under GNU GPLv2 Open Source license, with some parts released under LGPL and BSD licenses.

This is the nineteenth part of the ReactOS translation. There are some strings that were already translated. I'm translating the project file by file, so as I'm encountering those translated strings I'm fixing them or leaving them alone (depending on what needs to be done)
Subject to 
The project is being translated from English to Greek. I'm a native Greek and because of my job (programmer) English is a "must learn" language.
In this session I stumbled upon the biggest file of the project! It will take 5-6 parts to finish this file, if not more!
And his name is... rasdlg!
The longest translation in this session: https://crowdin.com/translate/reactos/3591/en-el#42024
It's not huge, but the original string is 98 characters, while the translation is 140 characters. Anything, to make sure the translation is well understood by everyone! :)
I translated 1201 words, minus an estimated 8% for duplicates and untranslated words, which brings us to ~1104 words, for a total of 22181 words out of 37669 words. All numbers were rounded to the nearest integer (as you obviously can't translate 724.24 words)

ReactOS is a great project, aiming to help the average Joe try a free alternative operating system, without having to change a lot of his habits. It has a long way to go though, as it is still in alpha development stage. I'm proud to translate this into Greek, as I've always been secretly supporting this project!
I have translated 1201 words (-8% for duplicates and untranslated words = ~1104 words) for a total of 22181 words out of 37669 words. I'm now translating libraries used to power your devices, as well as some internet and hardware related stuff.
