This entry is a user-made guide and not verified by any eMule developer, but is still a helpfull addition for most users. You you can find questions and comments on this topic in a dedicated thread on our forum.
Howto discover fake files
After doing a search, you can check a file immediately by using webservices. Go to Options/General/Edit Web Services... and paste in the following lines:
Power-Portal,http://ed2kstats.power-portal.to/ed2k.php?hash=#hashidIf your file isn't listed, you should check length/bitrate on plausibility and if provided different filenames for the file (only global search and kad)
Fake Check Bitzi,http://bitzi.com/lookup/ed2k:#hashid?ref=eMule
Reading filenames and comments
After you connected to some/all sources for the download, you can check the different filenames or comments. Comments or 2 different filenames should concern you.
A file downloading very fast with high compression (>100%) is often an indicator for a file filled with lots-of zeros. You should cancel these downloads immediately.
As soon as you downloaded the first 16 KBs, a preview can be successful. To enhance eMule's preview function, you should add the line
PreviewSmallBlocks=1 into the preferences.ini somewhere below "[eMule]" (emule may not be running when saving the preferences.ini!)
You can also create a file called "PreviewApps.dat" in the config dir, which could look like this:
VLC085=C:\Program Files\vlc\videolan\vlc.exeVideolan can be downloaded from here: http://videolan.org/vlc/download-windows.html and Media Player Classic here: http://sourceforge.net/project/showfiles.p...ackage_id=84358. Older and free versions of AcdSee (a fast and small image viewer) can be found here.
The advantage of the plugin is, that VLC shows all downloaded data. It is recommended to use the according partfile plugin v0.1.4 for VLC 0.7.2 http://prdownloads.sf.net/emule/vlc-0.7.2_...v-0.1.4_bin.zip or v0.2.1 for VLC 0.8.4a http://www.geocities.com/sibermutant/023_binary.html
Determing real file extension
Sometimes a file has the wrong filename. A 100% working method to find out the real extension is to look into the file using a text/hex editor. Most of the time, the first 3 letters suffice for identification. Here is a short list.
MZ=.exe (be careful with downloaded .exe files. You should always check them for viruses!)
Of course, you don't need to do any of the above if you use a link site like i. e. http://contentdb.emule-project.net/
