@Lukas_Macas - instead of accessing the file from share drive → you can copy the file to your local project temp folder ( Copy File activity) → process your request → after that delete the file (delete activity)…
this will improve your robot performance in reading the docs…
Like I wrote in first post - I have problem with downloaded file from network path - so that mean I copy file from network folder to Temp folder created inside Data folder of my running project.
