How can you read a filename but store a specific number within it?

Hi All,

I'm trying to analyse a bunch of files that have filenames like "1 crop 1, area - 122637", "1 crop 2, area - 88497" etc.

I need to store the numbers proceeding "area - " as a number and sum them for all the files within a folder.

Is this possible?

Thanks

'I need to store the numbers proceeding "area - " '

The word preceeding means "in front of". Do you really mean "following" ?

Which numbers do you want?

• 1 & 2 (i.e. preceeding area)
• 122637 & 88497 (i.e. following area)

What file extension do these files have?

hi Stephen, thanks for responding. "Proceeding" can also mean "originating from" and can be considered the opposite to "preceed". Apologies for the confusion!

To clarify, I used the word in the same context you have used the word "following"...so the latter case in your examples.

They have a .jpg file extension.

Many Thanks!

D = 'path to the folder where the files are saved';
S = dir(fullfile(D,'*crop*area*.jpg'));
[~,N] = cellfun(@fileparts,{S.name},'uni',0);
V = str2double(regexp(N,'\d+$','match','once'));
Z = sum(V)

thank you, that's worked a treat!
