File Information

Description

Lists the files in a directory and its sub directories.

Ok, so there are many functions like this one already on the file exchange, but this one uses a slightly different wildcard naming system that some people may find useful.

For example,

rdir('C:\Program Files\Windows*\**\*.dll');

will find all dll files in the directories starting with 'C:\Program Files\Windows' and all the dll files in the sub directories below them.

One can filter the list based on the file size and date.

Using the function to find files modified sometime today in the windows directory

rdir('C:\Win*\*','datenum>floor(now)');

Include the sub directories.

rdir('C:\Win*\**\*','datenum>floor(now)');

Or you could use it to find all the no zero-byte processed csv data files for the data recorded in April 2008.

rdir('data\test_200804*\csv\*.csv','bytes>0');

this finds files like...
data\test_20080401\csv\08h00.csv
data\test_20080401\csv\16h00.csv
data\test_20080402\csv\08h00.csv
data\test_20080402\csv\16h00.csv

13 May 2008	Dimitri Shvorob	Great job! Did what neither FUF nor DIRR (earlier FEX submissions) managed to do, and surprisingly fast, too.
12 Jun 2008	Dennis Olly	FUF was great, but failed on folders with a '.' in the name, eg '\recon_P20992.7\'. Rdir is excellent!
16 Jul 2008	Imaging Coderguy	I used FUF extensively in the past, and though it did the job, its slowness and quirks were problematic. RDIR on the other hand is so slick and well-made that it may as well be a mathworks-made function. Great work!
29 Jul 2008	Phillip Feldman	Excellent! Just what I was looking for. The double star syntax is a bit strange. I'd like to suggest that a slightly cleaner and more flexible mechanism for controlling the recursive searching would be an optional argument that specifies the maximum folder depth of the search.
