Close the other process that has the file opened.

The error is pretty clear. Something still has a handle on the file. Perhaps it's your code or perhaps you opened it to verify it was there.

This thing is pretty easy to investigate. Please see my past answer: how to compress the error 'it is already used by another process' in vb.net[^].

Thanks for your suggestion.

I have checked my matlab code ,where I close the file at the end of the file using fclose command.How cant I access that file if I close the respective .exe file .Can you show the code,since I am a beginner

What code? This is your who has code causing that problem, not me. If you can present a code sample, short but comprehensive, to reproduce your problem, it would really help. But first, use my advice and identify the point of blocking the access.
