File
Name: preferences.dat
Location: ~/.aMule/
Description
This file used to store eMule's configuration in it's earlier versions. Nowadays, it only stores the userhash and the configuration file version.
Data
The current configuration file version is 20 (in hex: 0x14).
Format
The file format is as follows:
VersionUserhashLengthFlagsShowcmdMaxpositionxMaxpositionyMinpositionxMinpositionyNormalpositionleftNormalpositiontopNormalpositionrightNormalpositionbottom
As you can see, all the fields are stored without any separator character. This is done like this because all the fields have a specific size:
- Version: 1 byte
- Userhash: 2 bytes
- Length: 4 bytes
- Flags: 4 bytes
- Showcmd: 4 bytes
- Maxpositionx: 4 bytes
- Maxpositiony: 4 bytes
- Minpositionx: 4 bytes
- Minpositiony: 4 bytes
- Normalpositionleft: 4 bytes
- Normalpositiontop: 4 bytes
- Normalpositionright: 4 bytes
- Normalpositionbottom: 4 bytes
The relevant fields are the following:
- Version: Specifies the configuration file version (the format defined in this articles corresponds to version 20).
- Userhash: The userhash.
- Length: Length in bytes of the file not counting th Version and Userhash fields (should be 38 bytes).
Once this data is put together, it is stored in little-endian.
Example
The following is a hex dump of an hypothetic preferences-dat file:
a3143e6f12dd445b12a0c3c6f7ca5b2d00230000000000000000000000000000000000000000000000000000
In the above example, the following data can be seen:
- Configuration file version: 20 (In hex: 0x14)
- Userhash: A36F3EDD125B44A012C6C3CAF72D5B23
- Other fields: Set to zero (0)
Extra
aMule ignores the main window position, main window size, length, flags and showcmd fields in this file. That's the reason why this fields aren't explained in this article.
All this ignored fields are set to zero by aMule. Even if they were set to some other value, aMule will never read those values. Instead, it uses the preferences set in ~/.eMule
