remove .srt files from videos.

[king1]

if these are files already on your PC (srt should be) you can simply browse to the folder that contains all these videos and use the search box in the explorer window...

search for
*.srt
(filename . extension - *= wildcard)

then when all the srt files show up
Ctrl A - select all
DEL - delete the selection...

Now if your previous process was embedding the subtitles in the video, such that there is no SRT file, you will have to redo the video OR turn off subtitles
