Refile backend that's based on Refile::Backend::FileSystem and stores files in sub-directories based on the given file id instead of storing all files on one directory.

Refile's out-of-the-box backend Refile::Backend::FileSystem stores all files within one directory which can get very large and makes maintenance (ls, etc.) very slow. This gem extends the default behavior, it splits up the directory in tiny chunks based on the given file id. For example if there is a file with id 0601ae4450cdc210ab9d05da50c392ee1c4b1894e8b2bc9cc5cc9e41e691 it stores the file in the nested directory 06/01/ae/44/0601ae4450cdc210ab9d05da50c392ee1c4b1894e8b2bc9cc5cc9e41e691 within the given directory.

Add refile-filesystem-hashed to your Gemfile.

gem 'refile-filesystem-hashed', '~> 1.0.1', require: 'refile/backend/file_system_hashed'

Replace Refile::Backend::FileSystem with Refile::Backend::FileSystemHashed.

backend = Refile::Backend::FileSystemHashed.new("/uploads")
backend.path('0601ae4450cdc210ab9d05da50c392ee1c4b1894e8b2bc9cc5cc9e41e691')
=> "/uploads/06/01/ae/44/0601ae4450cdc210ab9d05da50c392ee1c4b1894e8b2bc9cc5cc9e41e691"

You can replace Refile::Backend::FileSystem at any time as the gem will automagically move existing files to the new hashed directory structure.
