Files Used HelpNAV

During eMule's runtime quite a lot of files are used or created on first start. Most of them are created in eMule's config folder, others reside in the temporary directory as specified in the Options or directly in eMule's installation directory.

o
Known.met
The Known.met saves all files eMule knows of whether they are shared files, files currently in the download list or downloaded in the past. For every file information like file size, filename, hash sets, hash values and some statistics are saved. If you delete this file, eMule will have to rehash all files on the next restart. If you don't want eMule to remember downloaded files, disable the "Remember downloaded files" option in the preferences.
o
Known2_64.met
Stores AICH hashes of all downloaded and / or shared files. If you delete this file, eMule will have to rehash all files on the next restart. If you don't want eMule to remember downloaded files, disable the "Remember downloaded files" option in the preferences.
o
Known2.met
This file is not used by eMule anymore. If you do not plan to downgrade to an earlier version, you can delete this file.
o
Cancelled.met
All files which you started to download but then cancelled before completing are noted here, so eMule can mark those files to avoid redownloading them again. If you don't want eMule to remembercancelled files, disable the "Remember cancelled files" option in the preferences.
o
Clients.met
This file stores all users who have credits with your eMule
o
Server.met
Contains all known servers.
o
Emfriends.met
If users are added to the friends list they are stored in this file.
o
Preferences.ini
Saves all options set in the Options dialog and information about visual details like column size etc. Some development related and advanced options can only be enabled by editing this file, see this topic for details.
o
Fileinfo.ini
Comments or Ratings for your own shared files.
o
Category.ini
Stores the settings of your categories like name, comment and colour coding.
o
Ipfilter.dat
This file contains the IP ranges and access levels to be filtered by the IP Filter. Also see Options -> Security
o
Onlinesig.dat
The Online Signature is a small file which contains the server eMule is connected to and up- and download statistics. Can be used by IRC scripts or signature images.
o
Preferences.dat
Saves the user hash. This is a value calculated at eMule's first start and is used to identify this client in the network. Used for credit system and friends.
o
Sharedir.dat
Holds the paths to all shared directories.
o
Staticservers.dat
Static servers never change their IP and are theoretically always online in the network. These servers can be added to staticservers.dat by the context menu (right mouse button) of the server list. See also Options -> Server
o

Addresses.dat
eMule updates its server list at startup if valid addresses to server.mets are provided in this file. Options -> Server offers a button to edit this list and the option for updating at start up. The file may contain multiply entries (one on each line) but only the first address to deliver a valid server.met is used.

o
AC_SearchStrings.dat
Each search string that has been used is recorded and an auto-completing is offered if a new search matches previous ones.
o
AC_ServerMetURLs.dat
Same file as the the one above. The only difference is that this one is used to store entered URL to server.met files. Mind that many sites regularly change the addresses to their server.mets.
o
Cryptkey.dat
Contains the unique 384 bit private RSA key of your client to verify your userhash. If you delete this file, make sure to also delete preferences.dat which stores your userhash.
o
Collectioncryptkey.dat
This file only exists if you have created and signed at least one collection in eMule. It contains a unique 1024 bit RSA key, which will be used for all collections you are signing to verify that they are from the same author.
o
eMule.tmpl
The *.tmpl files are required for the Webinterface. They define layout and options of the displayed pages.
o
xx.part
Part files are unfinished downloads. eMule is able to download from more than one user at the same time, so the *.part files always have the size of finished download. Missing parts are simply filled with zero. In recent versions, and when using the NTFS filesystem, you can enable to option to share incompleted files as 'sparse', which prevents this behaviour and in doing so saves filespace.
o
xx.part.met
Every *.part file has a corresponding *.part.met file. To identify a download in the network and to check for errors each download is divided in about 9 MB parts. For each part a so called hash value is calculated. Then a new hash value is created of the complete set of these part hashes. This information together with the file name and the status of the hashes are stored in the *.part.met files.
o
xx.part.met.BAK
A backup of the *.part.met files is created as it is very bad if such a file gets corrupted by a crash. See Troubleshooting for help, if your downloads vanish due to corrupted *.part.met files.
o
eMule.log
Saves the output of the Log window in the Server pane if the appropriate option in Options -> Extended is turned on
o
eMule_Debug.log
Saves the output of the Debug window in the Server pane if the appropriate option in Options -> Extended is turned on
o
src_index.dat, preferencesKad.dat, nodes.dat, key_index.dat, load_index.dat
Those files are used by Kad and contain infromations about known nodes, keywords, preferences etc.
