If you know the repository name and file path where the file is stored. To obtain the file content saved as a stream, utilize the data page D pxGetFile in a data transform or activity.
The get file API is a read-only data page, D_pxGetFile. This API loads content or a stream to a file when the data page is loaded.
To use this API, define the following parameters:
- repositoryName – the name of the repository from which to get the file.
- filePath – the path, including the name of the file, to be retrieved, relative to the root path of the repository.
- responseType – the type of content that is in the file to be retrieved, either "STREAM" or "STRING"
Please refer the below link for more information on D_pxGetFile.
https://docs-previous.pega.com/data-management-and-integration/85/get-file-api?
Now to display the file on click of a link or button. Do the following.
1. Call an activity or data transform to trigger the D_pxGetFile data page.
2. Store the full path of the file in the format data:image/gif;base64,Param.Path. ( Refer attachment)
3. Use a non-auto generated section to display the file.

Note: When you use the get file API, D_pxGetFile, the file content is loaded into memory as a base-64 encoded string. When the size of the file to be read is larger than 45 MB, an exception is thrown and the content is not loaded into memory. You can configure the maximum file size by using the repository/maxFileSizeInMemory dynamic system setting in the Pega-IntegrationEngine ruleset.
Approach 2: If you want to preview & download the PDF, then do the following.
1. After retrieving the base 64, convert it to byte array using function(recommended) or java step.
2. Call Call Code-Pega-PDF.View to view & download the PDF file
Hope this information is helpful.
