select .txt file using a filter like *.txt

4 views (last 30 days)
Hey Experts,
I want to select a .txt file from a directory. In this directory there is only one .txt file among a bunch of image files. Each time the name of the textfile is different. So I want something like: fopen *.txt I looked everywhere but I cannot find a solution for this on first sight easy problem.
Many thanks! Marten

filePattern = fullfile(yourFolder, '*.txt');
textFiles = dir(filePattern);
If length(textFiles) == 1 then you know there's just one and you can grab that one. If the length > 1 then you might have to let the user select it with uigetfile() or else somehow figure out which one you want from the filename.

I am not sure if this is the simplest way. But you can use 'uigetfile'. Here you can use the .*txt filter. And then use the filename to open the text file.
