And if server is set to sv_pure 1, to allow clients use this file on server...
edit pure_server_whitelist.txt
You find this file from hl2 folder
Example allow knifefight sound

    //
    // 3 modifiers are allowed on file specifications:
    //
    //    from_steam            - only check the Steam cache for the file (ignore anything on disk)
    //    allow_from_disk        - allow the file to come from disk
    //    check_crc            - used with allow_from_disk - server does CRC checks on the client's file to make sure it matches
    //
    //    The default modifier on all files is allow_from_disk. Thus, all files can come from disk and don't need CRC checks unless 
    //    allow_from_disk can be set at the same time as check_crc. Use the + character in between them to signify this: allow_from_disk+check_crc.


    //
    // Three types of file specifications:
    //
    //    1. directory\*.*            - refers to all files under the directory
    //    2. directory\...            - refers to all files under the directory and all directories under that (recursively)
    //    3. directory\filename        - refers to a single file
    

    //    
    // By default, when in pure server mode, most content file types are only allowed to come from Steam.
