How do I read all text files from a folder?

Question

0 个投票

Hey all, I have four folders with text files in them in my workspace which I want my script to read into. I have tried using dir and fopen but fid = (-1). Here is the outline:

dirlist = dir('*/*.txt'); len=length(dirlist);

for K = 1: len fid = fopen(dirlist(K).name);

it says 'No such file or directory'. However dirlist indeed consist of the names of all the textfiles.

I notice you use a forward slant (/), so you must be using Linux. On Windows systems, the first two outputs from a dir call are:

.
..

and will throw that error. Check to see what ‘dirlist’ actually returns to be sure all the data returned are valid file names. It would likely be best to display the results of:

FileName = dirlist(K).name

for diagnostic purposes until you discover the problem.

(I am not listing this as an Answer because I do not have Linux to test this myself.)
