I get the follwoing error when using copyfile

The system cannot find the path specified.

I am using the following code

 source='D:\Research\Thesis_work\Structural_uncertainty\data_collection\Precipitation\precip_hourly\p_39.3130_-87.3130.txt'
 destination='D:\Research\Thesis_work\Structural_uncertainty\MatLab_codes\20180222\huc_0512011115\rainfall_data_hourly\p1.txt'
 copyfile(source,destination)

is there anything wrong with the code or is it a some MATLAB bug?

Hello,

I have a problem. I want to run an already code but the message that appears is "the system cannot the path specified".

Has it a relationship with clusters? I don't understand.

use exist(source,'file') to see if the file exists first. Your source file name contains multiple "." and "-'

then you need to check

[p,f]=fileparts(destination);
exist(p,'dir');

I see. It worked. I was using mkdir to create the destination folder in a wrong way, that's why destination folder didn't exist. I should have thought about it myself. Thanks a lot!

You have the wrong syntax for Asource. You are using remote file naming, which requires the general form

\\server\share\path\file

You have the server, 11.11.11.11, but then you skip the share and path and go directly to the file a.png

It is not really clear that copyfile supports remote file naming.

In any case you need

copyfile(Asource, Bdes)

Your current command is the same as

copyfile('Asource', 'Bdes')

because of Command-Function duality; https://blogs.mathworks.com/loren/2013/05/22/duality-between-function-and-command-syntax/

Matlab code is case sensitive, so make sure about the exact spelling within your OS. Moreover, you can try loading or reading and writing of such path into the source and destination file Use fprintf is another alternative

MATLAB code is case-sensitive, but the question has to do with difficulty with files . Whether any particular file name is case sensitive or not depends upon the way the particular file system is configured.

By default, NTFS (Windows) and HFS+ (MacOS) and APFS (MacOS) are not case-sensitive file systems, but all three of those can be configured as case-sensitive.

(Apparently these days on Windows 10 you can enable case sensitivity for individual folders; https://www.windowscentral.com/how-enable-ntfs-treat-folders-case-sensitive-windows-10 )
