Thank You Adrian Welsh. I am using Arcgis 10.1 version and I wanted to transfer .mxd document to other computer . But once you transfer it, you are not able to see the activated layers. Layers are disable. (This .mxd format basically support only with the computer you creating that document. You can not see that file, copying in another computer).
The solution you showed was helpful. Thank You. I think the best way to transfer .mxd document to other computer with all features, is sharing it as Map Package using Arc Online.
And following option is also to activate the disable layers and you have to transfer shape-files as well for this one.
