Preparing data:
|
||||
---------------
|
||||
### Preparing data:
|
||||
Nothing specific needs to be done. You can edit ypur tags, rename files, move

them around how you see fit. However, make sure you setup your tag editor
|
||||
to *do* update the files' timestamps: though it was initially plan to make this

optional, using checksums or tags, it was abandoned due to the huge amount of

IO required.

|

## Technical details
|
||||
### I. Source scan
|
||||
After reading its configuration file, AtOM uses find to get a list of all files
|
||||
in the source directory.

||||
Each file is checked against the database. If it's already there, and its last

II. Obsolete files
|
||||
------------------
|
||||
### II. Obsolete files
|
||||
Using the last_seen field, AtOM removes from destinations each files which are
|
||||
not present anymore in the source directory. AtOM never touches files not
|
||||
present in its database (unless there is a filename conflict, in which case your

||||
file *WILL* be overwritten). If you wish to clear unknown files from your

||||
destinations, have a look at toys/cleandestinations.
|
||||
|
||||
III. Reading metadata
|
||||
---------------------
|
||||
### III. Reading metadata
|
||||
AtOM then tries to read metadata from each new or changed file. It also re-reads
|
||||
metadata from files scanned with an older version of AtOM, if the parser for
|
||||
that format has changed. The actual data read depends on the format, but at the

## Toys

AtOM requires a database to function. Now that we have a database containing

various information about our media files, why not use it?

AtOM comes with a small set of tools in the toys/ directory. These are

documented in toys/README.
