Notation: When using PSCP to transfer files between your computer and your EC2 example, your "PuTTY Private Key (.ppk)" file must be in the folder you are working in, or you lot must provide a path in the PSCP control to the folder the file is located. For example, if "AWSkey.ppk" file is stored in the binder named "keys," include this path in the PSCP control:

C:\Users\username\keys\AWSkey.ppk

Re-create a File Into Your EC2 Instance

At the Windows command prompt blazon (notice where spaces are placed):

C:\> pscp -i yourkey.ppk yourfilename ubuntu@public_DNS:/home/ubuntu/

Example: To motility the file S1A_EW_GRD.zip from your Windows Downloads binder to the /abode/ubuntu directory of your EC2 instance.

1. 1. Utilize Windows File Explorer to move your awskey.ppk file to your Downloads folder, or provide a path to the folder your.ppk file is located in.
   2. At the Windows control prompt, navigate to your Downloads folder using the change directory (cd) control:

C:\Users\current_user>cd Downloads            and press Enter

1. 3. At the control prompt, blazon the PSCP command, which includes your .ppk filename (and path if necessary), the name of the file you lot desire to transfer, the "Public DNS" of your EC2 example, and the path to a binder in your instance:

C:\> pscp -i awskey.ppk S1A_EW_GRD.zip ubuntu@ec2-52-89-147-172.us-east2.compute.amazonaws.com:/home/ubuntu/

Control syntax (brackets indicate optional paths to your .ppk file and the file y'all want to move if they are not in the binder yous are in):

Windows command prompt — copy a file into your EC2 instance.

C:\> pscp -i C:\<path>\yourkey.ppk C:\<path>\yourfilename ubuntu@public_DNS:/home/ubuntu

Re-create a File Out of Your EC2 Example

At the Windows command prompt blazon:

C:\> pscp -i yourkey.ppk ubuntu@publicDNS:/domicile/ubuntu/yourfilename C:\[local_destination_path]\[folder]

Note that the .ppk file must be in the folder you run the command from, or y'all must include the path to the file in your PSCP command.

If you don't include a local destination path and folder in the control, the file will download into the folder the command is run from. In this case, the command syntax would be:

C:\> pscp -i C:\[path]\yourkey.ppk ubuntu@publicDNS:/domicile/ubuntu/[folder]/filename

Example: Move a product generated from an application out of your EC2 example PRODUCT directory to the Data binder on your Windows calculator.

1. 1. Apply Windows File Explorer to move a copy of my awskey.ppk file to your "Data" folder, or provide a path to the folder your.ppk file is located in.
   2. At the Windows control prompt, navigate to your "Data" folder using the change directory (cd) control:

C:\> cd Data           and press ENTER

1. 3. At the command prompt, blazon the PSCP control, which includes your .ppk filename, the Public DNS of your EC2 instance, and the name of the file you want to transfer.

C:\> pscp -i awskey.ppk ubuntu@ec2-52-89-147-172.us-east2.compute.amazonaws.com:/home/ubuntu/Product/F2_unw_phase.tif C:\data_files

Windows command prompt — transfer files.

Command syntax (brackets indicate optional paths to your .ppk file and the file y'all want to move if they are not in the folder yous are in):

C:\> pscp -i C:\[path]\yourkey.ppk ubuntu@public_DNS:/domicile/ubuntu/[path]/yourfilename C:\[local_destination_path]

Important: Files must be transferred from your EC2 instance to your figurer before yous terminate the instance!
