.TLINE File Extension
What is a TLINE file?
A TLINE file is a data file exported by zSnout TimelineOnline, an online program used to create timelines of events. It contains information about one or more events and dates in plain text, with each event separated by a line break.
You will only encounter TLINE files if you create timelines with TimelineOnline and export them. To export the file, select "Export/Share this Timeline" in TimelineOnline.
Since TLINE files are saved in plain text, you can open the files with any text editor, such as Microsoft Notepad or Apple TextEdit.
