  • I wanted this, but changing it in a string ... in this case video0, the next video would be video1 etc. I didn't understand what you wrote sorry xd – FRango SStYle Mar 28 '20 at 22:45
  • Do you have a loop on your code or you're talking about the next time you run the script? – Pedro Lobito Mar 28 '20 at 22:46
  • hmm not really wwii – FRango SStYle Mar 28 '20 at 22:46
  • I have a loop, but every time I run the script I want it to keep the name of the video incrementing 1 – FRango SStYle Mar 28 '20 at 22:47

  • If you've a loop, add it your question. – Pedro Lobito Mar 28 '20 at 23:04
  • i dont have a loop for that, just want a funtion that increment 1 the filename, every time run the script – FRango SStYle Mar 28 '20 at 23:06
  • "***I have a loop, but every time I run the script I want it to keep the name of the video incrementing 1***" then, couple of minutes after "***i don't have a loop for that, just want a function that increment 1 the filename, every time run the script***" , you're wasting everyone's time, including yours. – Pedro Lobito Mar 28 '20 at 23:11
