# CopyStepDetails


Each step type has its own `StepDetails` structure.

## Contents


 ** DestinationFileLocation **   <a name="TransferFamily-Type-CopyStepDetails-DestinationFileLocation"></a>
Specifies the location for the file being copied. Use `${Transfer:UserName}` or `${Transfer:UploadDate}` in this field to parametrize the destination prefix by username or uploaded date.  
+ Set the value of `DestinationFileLocation` to `${Transfer:UserName}` to copy uploaded files to an Amazon S3 bucket that is prefixed with the name of the Transfer Family user that uploaded the file.
+ Set the value of `DestinationFileLocation` to `${Transfer:UploadDate}` to copy uploaded files to an Amazon S3 bucket that is prefixed with the date of the upload.
**Note**  
The system resolves `UploadDate` to a date format of *YYYY-MM-DD*, based on the date the file is uploaded in UTC.
Type: [InputFileLocation](API_InputFileLocation.md) object  
Required: No

 ** Name **   <a name="TransferFamily-Type-CopyStepDetails-Name"></a>
The name of the step, used as an identifier.

 ** OverwriteExisting **   <a name="TransferFamily-Type-CopyStepDetails-OverwriteExisting"></a>
A flag that indicates whether to overwrite an existing file of the same name. The default is `FALSE`.  
If the workflow is processing a file that has the same name as an existing file, the behavior is as follows:  
+ If `OverwriteExisting` is `TRUE`, the existing file is replaced with the file being processed.
+ If `OverwriteExisting` is `FALSE`, nothing happens, and the workflow processing stops.
Type: String  
Valid Values: `TRUE | FALSE`   
Required: No

 ** SourceFileLocation **   <a name="TransferFamily-Type-CopyStepDetails-SourceFileLocation"></a>
Specifies which file to use as input to the workflow step: either the output from the previous step, or the originally uploaded file for the workflow.  
+ To use the previous file as the input, enter `${previous.file}`. In this case, this workflow step uses the output file from the previous workflow step as input. This is the default value.
+ To use the originally uploaded file location as input for this step, enter `${original.file}`.
