Hi,
I am trying to extract .txt files from a list of files I created into a cell array. From there I want to put them in a directory that feeds into a loop. Can you help please?
Thanks

Yes, and notice that the ext will include the '.' so Adam is correct in saying to compare against '.txt' rather than 'txt'

If YourCell is a cell array of strings that represent file names, then
is_txt_file = ~cellfun(@isempty, regexp(YourCell, '\.txt$'));
this will give you a logical vector that you can use such as
txtFileNames = YourCell(is_txt_file);
After that you can process them however you like.
If what you have is a dir() result and you want to pick out the txt files from that, then supposing DirInfo is the directory structure,
YourCell = {DirInfo.name};
is_txt_file = ~cellfun(@isempty, regexp(YourCell, '\.txt$'));
txtDirInfo = DirInfo(is_txt_file);
