anyone can tell me how to using a lan cable to share  file from PC to PC directly...without using a router??can it work???

thx ....

You will need a cross over cable, and you might need to configure IP address manually on both PC.
For the rest, will be the same as file sharing over router.

i have a pc to pc cable already.....but how to config the ip manually ???thx

2. 新增不同電腦的username及 password 在各電腦上
   例如有2部電腦, 分別名稱為PCA 及 PCB 使用者為 UserA 及 UserB
   那麼便電要在PCB上加入 USerA使用者, 而 PCA 上亦需要加入 PCB使用者
   可參考下面Link以參考增加user 方法
  how many user i need the 2 computer ??sorry i have a little bit dun understand...
i want to use wireless to the interet and cable to share file...am i need to stop the wireless??

唔需要stop wireless
可以照用
你有2部機
咁通常就係2個user
咁你就要將對方個account 加入在自已部機上就得

sorry .how to  將對方個account 加入在自已部機上???
