Steam – copy steam counter-strike source to second location

counter-strike-sourcesteam

both my friend and i have purchased steam cs source. i downloaded all 2.4 gb of it but due to internet issues, he could not. i was wondering what would happen if i copy the entire game folder (240) and pasted it on his own computer. he would login on his own pc with his own steam account, and i can save him the lengthy downloads seeing that we also bought cs go.
i can not simply try without being sure of the outcome in fear that i might mess up my account.
my question is would this cause issues of conflicts or blacklisting of any sort?

It would cause no issues in regards to your account.
To make this work, you would have to transfer the Counter Strike folder from steam\steamapps\common\ as well as the corresponding appmanifest_XXXX.acf (should be appmanifest_240.acf for CS:S) file from steam\steamapps\.

It's also possible to ignore the appmanifest file and just choose to download the game after you have the files transferred, which would trigger file verification and create appmanifest_240.acf automatically, but I have seen this fail, so I would recommend transferring that file as well.
