dir find no files ?

I used the function "dir" to get all the file names within a certain directory in a loop.
The directory is changing in the loop, but the files in each directory are same. What is weird is that the "dir" find no files in one of the directories while acturally there are several files in it. Then I check the directory independently(not in a loop) and the "dir" find those files. I don't know why. The memory full ?

Impossible to say. How, specifically do you call DIR? Are you certain that
the way you're actually calling it is the way you think you're calling it?
For example, there's a difference between:

D = dir('abc*')

and

D = dir('abc')

Are you sure you're calling DIR in the correct directory? Being one level
higher or lower in a directory structure can make a huge difference on what
DIR can 'see'.
