Maximum number of files on a disk?

ruby-talk
1

Two further points:
1. Are all these filed in a single directory?
2. How new is the ubuntu? You're probably using the open source NTFS-g emulation, which is itself based on the FUSE filedystem. That ntfs-g component did have a bug that resulted in the operation unsupported error. It was fixed in a later version

Agreed spaces are no problem, but your file name is somewhat atypical.
Have you tried with a totally plain vanilla file name?

I cannot create any files ...This works again if I delete some file/folder.

Sorry to ask the obvious, but are you out of space on the disk (or
anywhere close to being out of space)?

Also, Tim makes a good point about files in folders. Although NTFS has
no limit on this, on older versions of NTFS, things got very slow if there
were more than a few thousand files in a folder. That's been fixed in
newer versions, but it's still a good idea not to put lots of files in the
same folder.

Good luck,

Wayne

For NTFS, the maximum number of files that can be created is 2**32 - 1.

I'd expect that the number for fat32 is similarly large.

Hope this helps,

Dear Wayne,

thank you for responding.
I am writing to an NTFS disk, where I am splitting up a large XML file into smaller
bits, which are saved as individual files ( and closed immediately after writing to them).
The process runs smoothly until I get the following last correct output

49'000'000 # <- number of lines traversed in the XML file so far (print every 500'000)
<current file title>
1483042 # <- smaller files written to disk so far

and this error:

lbwiki2.rb:114:in `initialize': Operation not supported - /media/Philips External Hard Disk/en_wiki/Warnock's\ Dilemma (Errno::EOPNOTSUPP)
     from lbwiki2.rb:114:in `new'
     from lbwiki2.rb:114
     from lbwiki2.rb:85:in `each'
     from lbwiki2.rb:85

In this line 114, there's a File.new for the next small file to be created. The spaces in the file name are no problem.
I am using Ubuntu 8.10 (32 bit) + ruby-1.8.7-p72.

I cannot create any files on the disk anymore, neither with Ruby nor on the command line. This works
again if I delete some file/folder.

So there must be some maximum amount of files that this NTFS disk can handle, which is way below 2**32-1 ...
What can I do here ?

Thank you very much!

Best regards,

Axel
