Who is this for?• New to Drupal?
• Starting a new Drupal site!
• Inherited a new Drupal site and want to know more about configuration
Wednesday, January 15, 14
In this demo• How file path patterns
affect maintenance and migrations
• File upload management
• Future friendly path patterns
Wednesday, January 15, 14
Source of the pain?• Drupal default file
field upload pops ALL files into the same directory
• Often overlooked by developers
• Significant performance impact
• Easy to prevent!
• ...not easy to fix!

Getting to grip with the basics
Wednesday, January 15, 14

• Per content type settings• Required?• Help text• Allowed extensions• File directory• Upload size• Description field• Progress indicator• Number of values
Wednesday, January 15, 14
Limiting file types• Security tip: Err on the side of less file

Fix existing file names
Wednesday, January 15, 14
How many is too many?
Wednesday, January 15, 14
The extreme limits• FAT32:• Maximum number of files: 268,435,437• Maximum file size: 4GB• maximum number of files per directory: up to 65535, or less depending
on file names• NTFS:• Maximum number of files: 4,294,967,295• Maximum file size: 16TB currently (16EB theoretically)• Ext2:• Maximum number of files: 10¹⁸• Maximum file size: 2TB• theoretical file per directory limit: 1.3 × 10²⁰ files• Ext3:• Maximum number of files: number of bytes in volume/2¹³.• Maximum file size: 16GB (1KB block) to 2TB (4KB block)•http://stackoverflow.com/questions/466521/how-many-
files-in-a-directory-is-too-manyWednesday, January 15, 14
What’s wrong?• Slow to load directory for maintenance and
migration• Performance hit loading files from that
directory
• Set Max at 1000 or 100,000- well below your “limit”
Wednesday, January 15, 14
File path patterns
Wednesday, January 15, 14
Configure file paths• Basic settings are
limited
• arbitary text
• entitytype/filetype
• Example: article/pdfs
Wednesday, January 15, 14
A better idea!• sites/default/files/YYYY/MM/DD• For high volume uploads
https://drupal.org/node/2128055Wednesday, January 15, 14
Token for file directory!• Set to date
Wednesday, January 15, 14
File (Field) Paths• Set file name also• Node tokens• Transliteration
Wednesday, January 15, 14
Example file path patterns• Parent directory by date• Parent directory by content type• Parent directory by a combination of content
type and author
Wednesday, January 15, 14
Pathauto• Requires Token• Set patterns for paths instead of node/1
Wednesday, January 15, 14
Private and public files
Wednesday, January 15, 14
public:// & private://• Public
• Anyone can download them
• Private
• Controlling access to the files
Wednesday, January 15, 14
Private• Specify a directory
outside of the doc root folder
Example../private
• OR Sub-directory under the public directory
Examplesites/default/files/private
https://drupal.org/documentation/modules/file
Wednesday, January 15, 14
Private directory• Create the private directory at same level as
root folder• Configuration > Media > File system• Set file system path
• System creates .htaccess file
Wednesday, January 15, 14
Choose default option• Configuration > Media > File system• Choose default method
Wednesday, January 15, 14
Per field options• Select private file
• The paths will be like /system/files/ebooks/pressrelease.pdf
Wednesday, January 15, 14
What happens?• Field inherits access publishing settings of
content
Wednesday, January 15, 14
Private file modules• Private files download permission 1.7k using• Field Permissions 36k using • File entity (fieldable files) 29k using
Wednesday, January 15, 14
More complex file handling needed?
Wednesday, January 15, 14
A flexible solution• Media +
• File entity +
• OEmbed +
• CKEditor
• Being used in Drupal Commons and Demo Framework

Fix it? HALP!
Wednesday, January 15, 14
Remediation • Move files to new directories• Recreate all the files using your new tokens• If you embed “inline” files/images, you’d
have to write a script to find and replace.
• Public files are easier.• Drupal handled files are easier.• Example: Media is embedding a file ID.

migrate of your own site.
