file doesn't exist

[buran]

If the both scripts are in the same folder and this folder is the current working directory from which you run the scripts received should be subfolder.

because you have this line os.chdir(os.path.abspath(os.path.dirname(__file__))) which I removed in my scripts, I guess your current working directory is the folder in which your files are

of course you can specify absolute path where to save the received file in which case it will doesn't matter
