Preferences.dat file
Contents
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:
VersionUserhash
As you can see, both are stored without any separator character. This is done like this because the version number has a static size of exactly two chars.
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:
a3143e6f12dd445b12a0c3c6f7ca5b2d
In the above example, the following data can be seen:
- Configuration file version: 20 (In hex: 0x14)
- Userhash: A36F3EDD125B44A012C6C3CAF72D5B
Extra
Version 20 format allows also to store the main window placement of the app right after the userhash, but aMule doesn't use it.
