Seeds, Peers and Leechers
- In Short, Seeders are that the downloading of particular torrent is uploading for another client system who want to download it.
Peers : A peer is one instance of a BitTorrent client running on a computer on the Internet to which other clients connect and transfer data. Usually a peer does not have the complete file, but only parts of it. However, in the colloquial definition, "peer" can be used to refer to any participant in the swarm (in this case, it's synonymous with "client").
It Means, total users who are downloads the particular torrent.
Leechers :
- A leech is a term with two meanings. Usually it is used to refer a peer who has a negative effect on the swarm by having a very poor share ratio (downloading much more than they upload). Most leeches are users on asymmetric internet connections and do not leave their BitTorrent client open to seed the file after their download has completed. However, some leeches intentionally avoid uploading by using modified clients or excessively limiting their upload speed.
- The often used second meaning of leech is synonymous with downloader (see above): used simply to describe a peer or any client that does not have 100% of the data. This alternative meaning was mainly introduced by most BitTorrent tracker sites.
- - It Means, The Persons who are only downloading, they do not uploading for other users.
--> Peers mean : Number of people are downloading and as well as uploading.
--> Leech : Number of people are only downloading.. Not Uploading..

Oprating system file
FAT(File Allocation Table) A file system that is used by MS-DOS and other Windows-based operating systems to organize and manage files. The file allocation table (FAT) is a data structure that Windows creates when you format a volume by using the FAT or FAT32 file systems. Windows stores information about each file in the FAT so that it can retrieve the file later.
FAT32A derivative of the FAT file system. FAT32 supports smaller cluster sizes and larger volumes than FAT, which results in more efficient space allocation on FAT32 volumes. See also: File Allocation Table (FAT),NTFS File System,Volume
NTFS
NTFS File System An advanced file system that provides performance, security (i.e.,file and folder permissions), reliability, and advanced features that are not found in any version of FAT. For example, NTFS guarantees volume consistency by using standard transaction logging and recovery techniques. If a system fails, NTFS uses its log file and checkpoint information to restore the consistency of the file system. In Windows 2000 and Windows XP, NTFS also provides advanced features such as encryption, Reparse points, Sparse files, USN Journal, and disk quotas.
