In that error message, one of the components of the directory name is "Frames". However, when I look closely at the spacing, it looks to me as if there might be a space between the e and the s, "Frame s". Compare the spacing between the characters in that part of the error message to the spacing between the e and s in "images" later in the error message.

Well, I guess you deleted or moved the image files...?

I am using 500 frames to analyze high speed velocity is it optimum number of frames for PIVlab?

That depends an many parameters, I would recommend that you post example images and your setup in the PIVlab forum.

I attached the PIV setting the frames are 500 I cannot attach all. so I only attach 200. How can I send you PIV session which I save for the results. For data I am collecting almost all the parameters.

You should increase the frame rate and increase the seeding (= amount of particles). You need to have at least 5-10 particles per interrogation area to get good results.
