wy changing template of one srt file, changes the default of al txts

HI, Srt files could be edited a text files in notepad. BUt there is a problem in doing so. Changing the default template lilke font change and size, it affects all the saved txt files in my pc.
Is there any fix for this
If i copy and changes the font in word and then copy to notepad, it is again the same. All the changes are lost and defaut notepad settings are shown.
Srt files could be edited, but how to keep the custom font size to one txt file.
srt files cannot be stored in another format
please give me the solution

Txt files, as well as their subtitle cousings .srt files are plain-text, and containt NO information about font size, color, typeface or anything, they're just text.

Notepad is also a very basic text editor, and doesn't support any kind of formatting, much less per file. Changing its settings will have global effect and will affect any file opened.

RTFs can carry some formatting.

Well, yes, but they're beyond the capabilities of notepad.

Hi, sorry for late coming. i was not informed thro emails of the posts.
If i change the font in word and then copy to notepad , it changes back to default notepad settings.
this is the problem. srt files could be edited as plaint text, for which i used it and this cannot be saved as word files as per the format that video will take.There should be some solution to this behaviour .
