How to copy a video file from an external drive to the current workspace?

I am working on a script which will loop through a group of large videos that I have on an external drive. In psuedo codo I want to:

loop for all files

copy video to current workspace (to increase reading speed)

open video visually

mark certian frame and time stamps

close video & delete local copy

end loop

I have most of this working except I cannot get the copyfile function to work for me, here is what I have written -- any help would be great

[file,path] = uigetfile('*.avi');

name = join([path,file]); % This is a char

CurrentDirectory = 'C:\Users\username\Desktop\Currently Working On'; % this is a char

copyfile name CurrentDirectory;

%% -- ERROR MESSAGE -- %%

% Error using copyfile

% No matching files named 'C:\Users\username\Desktop\Currently Working On\name' were

% found.

What I think is the issue you're experiencing is due to passing the variable "name" as a literal string instead of its value. To fix this, you need to concatenate the value of name with the destination directory. Here's the corrected code:

[file, path] = uigetfile('*.avi');
name = fullfile(path, file); % Create the full file path
CurrentDirectory = 'C:\Users\username\Desktop\Currently Working On';

copyfile(name, CurrentDirectory);

By using the "fullfile" function, you ensure that the file path is constructed correctly, taking into account the operating system's file separator. Then, you pass the "name" variable (which holds the full file path) and the destination directory to the "copyfile" function. You may refer to this fullfile & copyfile documentation.
