Files are probably the most important part of AniDB's structure. They are what gets added to users mylists in order to mark episodes watched.  
AniDB stores information ([http://en.wikipedia.org/wiki/Metadata metadata]) about digital files that at some point in history has been released on the Internet. This information is an integral part of AniDB and for many users the most important reason for using AniDB. Note that AniDB does not, never has and never will, have any copies of these files. Read the [[AniDB:General_disclaimer|general disclaimer]] for more information on this.


Since files in AniDB are tied with an actual episode, the place where you add files is at the far right of each episode entry. Click the "add file" icon that looks like this: [[Image:Anidb file add.gif]], and it will take you to a new page where you can fill in the information about the file you want to add. For video files, the most important fields are: '''ED2K-link''', '''CRC'''/'''CRC Status''', '''Release group''' and '''Audio''' and '''Subtitle languages'''.
As a user you do of course not have to use any feature related to files; AniDB offers many features that are completely unrelated to them. There is also the concept of ''generic files'': If you want to add an anime to your mylist, but watched it on TV, have it on DVD or just don't care about registering actual files, see [[Files:Generic files]].


Alternatively you can use the [[Mass_add:Files|mass add file page]] which is linked at the bottom of every anime page (massf).
==Content==


==Content==
===Release information===
===Release information===
Information related to the actual ''release'' of the file: ''group'', ''relase date'', ''CRC status'' and ''version''. If the origin of a file is unknown, i.e. ''no group'', then none of these fields have any meaning and should therefore not be set.
====Group====
====Group====
Normally, the files are "tagged", meaning that the filename contains a string like "[AonE]" which you can look for in the according shortname dropdown-menu. Please note that not all groups on AniDB are listed under the tag they actually use, as AniDB can only have one distinctive tag for each group. '''So make sure the group's full name matches as well'''.
AniDB stores the name and short name of the group/person that produced and released a file. The short name is usually found as ''tags'' in file names, for example "[AonE]". Please note that not all groups registered in AniDB are listed with the tag they actually use, as AniDB can only have one distinctive tag for each group.


When you add a new file from a group that already have some files added for this anime, you can save yourself from going through the extra step of searching for the group again and again by using the '''by relation''' list, that contains only groups that already have at least one file added for this anime.<br>
'''Note:''' If a file is a joint release, like a file by e.g. ANBU-AonE, that joint group has its own group entry. The file should not be registered under either ANBU or AonE, but to the group that combines them both.
Otherwise, you have to search for the group.
 
If the group isn't listed, you have to [[Content:Groups|add it first]].
 
'''Note:''' If a file is a joint release, like a file by e.g. ANBU-AonE, that joint group has its own group entry, so you should not add the file to either ANBU or AonE, but to the group that combines them both.


'''Note:''' If the file is a RAW, you should check [[which RAW groups to credit]].
'''Note:''' Not all RAW groups are credited. See [[which RAW groups to credit]].


====Release date====
====Release date====
The date the group published the file. Have a look at the group's homepage or other release info pages like [http://www.envirosphere.com/ Envirosphere] or [http://baka-updates.com/ Baka Updates].
The date when the group released the file. Usually provided on the group's homepage or on some other release info site like [http://www.envirosphere.com/ Envirosphere] or [http://baka-updates.com/ Baka Updates].


====CRC status====
====CRC status====
Most groups release files with corresponding CRC32 checksums; in the filename, in a sfv file or on their web page. If the calculated CRC32 sum of the physical copy in your possession matches the sum provided by the group then set the status to ''matches the official CRC''. Otherwise, set it to ''does NOT match the official CRC''. It is not possible to use these states if no CRC sum is registered in AniDB.

If no sum is provided by the group or if you can't bother to compare, then set it to ''not compared to the official CRC''.
If no sum is provided by the group or if you can't bother to compare, then set it to ''not compared to the official CRC''. If no CRC sum is registered in AniDB then this field has no meaning and can be ignored.
 
'''Note:''' If the file is a ''no group'' file, '''do not set crc correct status!''' Most raw files come from [http://en.wikipedia.org/wiki/Share share] or [http://en.wikipedia.org/wiki/Winny winny] hence no official crc is known!

====Version====
====Version====
Sometimes, the group makes mistakes and wants to correct them by releasing a second (third, fourth...) version, usually called "v2" ("v3", "v4", ...). If there is no such tag in the filename, it's normally "version 1".
Sometimes the group makes mistakes and wants to correct them by releasing a second (third, fourth...) version, usually called ''v2'' (''v3, v4, ...''). This field is usually based on information in the file name (where no information normally means ''version 1'').


'''Note:''' For standardization purpose if the source changes the versions gets set back to v1.
Even if a group releases two files of the same episode it does not mean that the first has to be marked ''v1'' and the second ''v2''. There are other reasons to do something like that other than correcting mistakes like; different source (DTV/DVD), different sub languages, high and low quality versions, etc.
:''Example: a group releases a file with source dtv. Later they release the same thing again from dvd. Both is to be considered v1!''

==Adding new files==
===Other information===
Other information that is set manually and in some cases disputable.
 
====Censored====
Mainly used for files with pornographic content.
 
===Source===
Here you can set the source of the raw (unsubbed) anime. If you don't know the source, leave it as "unknown". If you find a tag like "(S)VHS" or "DVD" in the filename, choose the according option from the dropdown-menu.
Sometimes, it's ok to make an educated guess: For animes that are released fansubbed shortly (within days/weeks) after they aired in Japan, you can safely assume "DTV" (Digital TV) as source. Another case for educated guessing is "HKDVD" (Hongkong-DVD) - the video-quality may be ok for them, but the translation is usually horrible, which is how you can spot them.
 
When creqing this field you should provide some sort of proof unless the old value is obviously wrong or set to "unknown". This means that you should be sure about the change and not just base it on assumptions. For example, don't creq DTV -> HDTV based on resolution/quality/filesize/etc. only.
 
===Quality===
Eyecancer, very low, low, med, high, very high.
 
*This is a very arbitrary field. It depends completely on the eye of the beholder. You should not put too much meaning into it, but rather use it as a general pointer of quality.
*This field should '''not''' be used to rate releases from different groups. Use anime-group comments/votes to express opinions about such.
*This field should be considered '''per''' group: When multiple releases exists from a group it can (and should) be used to differentiate them.
*Although there have never been any written rules; ''quality is usually bound to source''. Ie. DVD -> very high, DTV -> high, VHS -> low, etc.. It is generally ok to follow this scheme, but don't go about creqing just because of it. There are many good reasons for not following it.
*Note that 'very high' quality rating is not reserved for the theoretical perfect release, or bound to DVD source or anything like that. It can be used more freely to differentiate.
*If you want to request a change, check the history of the file first. It might have some useful information (discussion) about why the current rating was selected and save you from a humiliating deny.
*Feel free to discuss this system in our forum/channel, but '''never''' start a personal creqing spree to "reform" it.

==Removing file entries==
If you added a bad entry you can also remove it as long as no one else has added it to his/her [[mylist]]. Otherwise, you have to issue a delete request.
