The only way I could get it to work is to use the example at class Dir - RDoc Documentation and create a directory variable such as: lfiles=Files.join("C:", "Users", "Public", "Music", "Sample Music", "*.wma") and then use a=Dir.glob(lfiles).
The only problem with that approach is that the entire path is added to each file. I don't know if this is a concern or not.

Looking at the source code for Dir it looks like it should accept the above directory separators if the macro DOSISH is defined. Where is this defined? It looks like it is part of the build process so I would assume it would be defined if building for a Windows platform.

Further experimenting found two other solutions. The first is to use:

A better solution may be to use Dir.chdir to change to the directory and then use Dir.glob to extract the file names. This has the advantage of not including the path in front of each file name.

To avoid "." and "." how to use the Dir::glob() method? Give me an

Dir.glob("C:/Documents and Settings/prayer/My Documents/userdata/**/*")
Hi, there is a confusion with Dir::glob method:
irb(main):001:0>Dir.glob('C:/Documents and Settings/peter/My
Documents/userdata/Test/')
=> ["C:/Documents and Settings/peter/My Documents/userdata/Test/"]
But the 'Test' folder also have another folder like "aaa". why it is not
appearing in the output?

chdir is not thread safe, it changes the pwd which is global to the process. Here's an alternative:
d = Dir.new("/tmp") # use fwd slashes even on windows
d.grep(/\.wma$/)
This should give you an array of filenames in the dir.

For example : To process only the files in the directory and in its
sub-directories :
Dir.glob("**/*") {|x|
if File.directory?(x) then # it's a directory
else # It's a file ...
}

Is there a way to expand this to include subdirectories like .glob allows? .grep doesn't appear to work on the string created by File.join.
For example : To process only the files in the directory and in its
sub-directories :
Dir.glob("**/*") {|x|
if File.directory?(x) then # it's a directory
else # It's a file ...
}
Yes But if I want to perform such search,on the directory say -
"C:\Documents and Settings\prayer\My Documents\userdata" . Then how to
pass it to the Glob() method?
Part of the confusion may be what "glob" is doing. "glob" is a term
inherited from *nix shells, which often have some terse, strange terms
for things. While Dir.glob inherits some of the conventions, it also
expands on them. The basic premise, however, remains the same: return
things that match what I give, substituting where wild cards are
placed.
