Scanning a Volume

When given a volume to scan, here's what happens:

• FF reads the directory at the volume's URL
• For each item found, does "Each Entry" below.

Each Entry

• Looks for a matching entry in dirent.
• If entry does not exist, creates it.
• Logs that the entry was found, and whether it was new or existing.
• If it was an existing entry, logs any changes in the specs.
• If Entry is a File, does "Each File" below.
• If Entry is a Folder, does "Each Folder" below.

Each File

• Checks the firev to see if it matches.
  • If not, creates a new firev and updates the file's ID_Firev.
  • Logs whether the firev has changed or not.

Each Folder

• Checks to see if folder is scannable.
  • If it isn't, log that it was not scanned.
  • If it is, do "Each Entry" above for each entry in the folder's directory.
