whenever i Download a torrent from a .torrent file or magnetic link why does tixati shows file size larger than the original size (Mentioned on the website) but this is not the case with utorrent. Please help guys.....

Tixati uses proper base-1000 units for file sizes and speeds.  eg. 4KB = 4000 bytes , 4MB = 4000KB = 4000000 bytes

Some other clients are still using base-1024 units for everything.  eg. 4KiB = 4096 bytes , 4MiB = 4096KiB = 4194304 bytes

Many other clients don't even label the base-1024 units correctly like GiB MiB KiB etc...

If you really want base-1024 in Tixati, go to Settings > User Interface > Output Formatting

Thanks for this information but i'm curious about downloading few extra MBs than the original size of the file

OP, re-read the last reply... it explains perfectly

if a KB is smaller, MORE of them fit into the same file

a file that is 1,234,567 bytes

can be displayed as 1,205 KB if you are using base-1024 (some other torrent client)
OR
can be displayed as 1,234 KB if you are using base-1000 (Tixati)

looky: http://en.wikipedia.org/wiki/Kilobyte

if you are still confused, just change your settings like the other post says, then Tix will display the old-style units and they will match file-sizes with old-fashioned software

Settings > User Interface > Output Formatting

Bytes ---> Largest Unit  set to Ki
and also for Bytes In Charts right under it

Thanks for helping Mate....I was so confused.
