The ri documentation for FileUtils.rm gives several examples, among which you
can find this:
FileUtils.rm Dir.glob('*.so')
This removes all files with extension .so from the current directory. To
remove *all* files from the current directory, you need to replace '*.so' with
'*' (which matches all file names):
require 'fileutils'
FileUtils.rm Dir.glob('*')
If you want to remove all files from another directory, you do:
require 'fileutils'
FileUtils.rm Dir.glob('/path/to/dir/*')
Note that this will give you errors in case the directory also contains
subdirectories. In this case, the correct approach depends on what you want to
obtain
* if you also want to remove the subdirectories, replace FileUtils.rm with
FileUtils.rm_r, which also remove directories
* if you don't want to touch subdirectories and their content, you can do
something like this:
Dir.glob('*').each do |f|
FileUtils.rm f unless File.directory? f
end
* if you want to delete the files in the subdirectories but keep the empty
subdirectories, you can do this:
require 'find'
Find.find('.') do |f|
next if File.directory? f
FileUtils.rm f
end
I hope this helps

Your code seems correct. Since I don't use windows, I can't help you much
there. Seeing your commented out puts makes clear you already checked the file
names were correct (I'd also try with p rather than puts, to see the raw
string, just in case). Does the error happen for all files, or just for some
of them? Also, when you say you tried changing permissions, did you try only
on the files or also on the directory itself (provided that directories can
have permissions on windows. It's been some years since I last made serious
use of windows, so I don't remember)?

FileUtils.rm emulates the function of the Unix rm program.
FileUtils.rm_r and FileUtils.rm_rf emulate that program when using the
-r and -rf options respectively. The -r option (or _r) tells rm to work
recursively, to delete any subdirectories and their contents as well as
files in the selected directory. The -rf option (or _rf) is also
recursive but it adds a force option that will allow rm to delete files
that you own but which have been marked read-only. Take special care
with that one!

Have you tried removing one of those files by hand? If that works, then we now
the issue is with ruby. If it doesn't, you may get a clearer error message
and, at least, we'll know the issue is not with your code.

You're bumping into a common limitation of Windows, sadly. It takes
some special tricks to fake deleting a file which is in use on Windows,
and I'm not certain that FileUtils has been written to perform such
tricks. Note that I did say "fake deleting" since the file is not
really deleted until it is no longer in use. It's just cleverly moved
and hidden from what I understand.
Cygwin and the Cygwin build of Ruby should be able to do this for you,
but you are doing something which is not normal for Windows. Why do you
want to delete this temporary file while Mongrel is running in the first
place?

What I mean is that if you launch the file manager (clicking on the "My
Computer" icon, for example), navigate to the directory where your files are,
select one of them, press the Delete button on your keyboard and you get an
error message saying you can't delete the file (hopefully with an explaination
of why you can't delete it) then, of course, you also won't be able to delete
it from ruby. If windows thinks a file can't be deleted (or at least it can be
deleted only from the system administrator, for example), then it won't allow
you to delete it, and it doesn't matter whether you're using the file manager,
ruby or some other program to delete the file: they all have to use the same
functionality provided by windows to do so.

Yaa Jeremy i really need do delete those file..
In my rails application i am uploading some large file (2gb) and while
doing mongrel +ruby temp file is being created ,ruby temp files is not
the problem because they are garbaselly collecting after upload but
mongerl temprary files are sitll holding memory
that is why iw ant to delete them only after i restart mongerl i get
ridoff those temp files but i don't restart server
Thanks Stefano..
yaa when am trying to delete files manually am getting cann't delete
file .
It is in use....

Unfortunately, either Mongrel or your application is still using those
files; otherwise, you would be able to delete the files on Windows.
Even on non-Windows then, deleting the files won't reclaim the space
until after the program with the open file handles stops and releases
the files, so if consumption of disk space is your concern, you need to
find a way to close those files even if you manage to delete them.
I'm not familiar enough with Mongrel to give anything more than general
suggestions, so take this for what it's worth. Confirm that your
application is not causing these files to be opened and never closed by
way of a long-lived File instance referenced in one of your objects.
Maybe you can boil down your application to just this upload feature and
use that as a simple test case to prove that Mongrel is the one holding
onto these files. If the temporary file really is created by Mongrel
itself, perhaps there is a configuration option to tell Mongrel to
periodically dump its temporary files and create new ones.

Why? Are you running into file system limitations due to size and
number of files? Or are you just offended by temporary files on
principle, like I am?

doing mongrel +ruby temp file is being created ,ruby temp files is not

Does the Mongrel process handling the upload balloon up as well as
create a file that cannot be reclaimed?
If so, create a minimal app (as has been suggested), and see if you
can narrow down the problem. It is possible that a) either your Ruby
program is not garbage collected, or that Mongrel shows a strange bug
when dealing with large downloads.
