    26

  • Organizing

    Directory Structure:

    Easy to understand

    Representative of content

    Think about 10-years-from-now you, not current-you

    27

  • Organizing

    Tagging / embedding information (metadata):

    Adds meaning beyond file names

    Adds to search capability, especially for non-textual items (photos, video)

    May be more important to add metadata to certain formats (photographs)

    28

  • Organizing

    Common tags:

    Dates

    Subjects

    Location (GPS)

    Purpose

    Version

    29

  • Organizing

    A few tagging tools (these all embed metadata):

    Adobe Bridge

    Apple iPhoto

    Windows Photo Gallery

  • Storing

    Factors for choosing storage options include:

    Cost and time

    Quantity (size and number of files)

    Expertise (skills required to manage)

    Ready access vs. archive

    33

  • Storing

    Hard disk drives (spinning disk)

    Inexpensive per amount of storage

    Requires manual copying/maintenance

    Great for both files and complete system backup

    Less reliable than flash storage

  • Storing

    Solid State Drives (flash memory):

    More expensive per amount of storage

    Easier to transport

    Variable sizes and housing

    More reliable than spinning disk

  • Storing

    Cloud storage:

    Cost varies by service provider

    Often automatic backup/updating process, which reduces manual time

    Less privacy; read terms of service!

    Dependence on a third party (what happens to your content if they go out of business?)
