Question: I have Red Hat Enterprise Linux 5 installed on VMware workstation. I want to copy a file from desktop to usr/scr folder. I tried it the normal way i.e. copy/paste but it doesn't paste in the destination folder. Please help.

Answer: 
I think this question is not clear.

Guess your scenario:

```
---------------------------
|VM1(CentOS) | VM2(CentOS)|
---------------------------
|    VMware workstation   |
---------------------------
|       Your Computer     |
---------------------------

```

You want to Copy Desktop Data in \*Your Computer, it depend on the OS:

1. If OS is `Windows` => Using [WinSCP](http://winscp.net/eng/download.php)

`WinSCP` is a open source tool for windows, default is based on FTP/SFTP/SSH. 
The GUI is friendly, I think I don't need to guide you this.

2. If OS is `Linux` => Using [scp](http://linux.die.net/man/1/scp)

`scp` is a build-in command in Linux, default is based on SSH.

e.g. Assume your destination VM private IP Address is `192.168.0.1`

```
1. Copy file from desktop to target machine (default port 22)   
    % scp /path/to/desktop/file user@192.168.0.1:/path/to/usr/src

2. Copy file from desktop to target machine (setting port 5566)   
    % scp -P 5566 /path/to/desktop/file user@192.168.0.1:/usr/src

3. Copy directory from desktop to target machine (default port 22)
    % scp -r /path/to/desktop/Dir/ user@192.168.0.1:/usr/src

```

Of course, if you want to copy data from VM1 to VM2, you still can follow above.
This is the how you copy a file in a linux terminal:

```
cp <source> <destination>

```

You can also use man to get help and read more about linux-commands:

```
man cp

```

As piojo commented below you need root access to copy a file to the /usr-folder. To get root access you need to login as root-user or perform the copy command as root. Use man to read about su and sudo.

```
man sudo
man su

```
