The YWL file extension is linked to YoWindow Data and belongs to the categories of Data Files and Developer Files, which include 7362 files.

The YoWindow Data (YWL) was developed by Repkasoft, which created file format and programs to work with them.

YWL files are supported by Windows. To open a YWL file, you can choose from 5 programs such as Notepad++, Windows Notepad and Sublime Text.
