Export work item attachments to a directory
We have a requirement to export work item attachments to a server location.
Here is what we have done
1. Browse through link-attachment instances get pxLinkedRefTo for each instance.
2. Pass the pxLinkedRefTo as parameter to Obj-Open-By-Handle
3. Decode pyAttachStream using Base64Decode function and set it to a property.
4. Call connect-file with write from clipboard property
Issue: the text files are exported and could read them but couldn't read excel or word files or Images, I have tried by changing the file extensions as well.
Please assist us decoding and exporting these attachments.
Attached the activity written for the same. Any help is much appreciated.

What type is the '.Temp' Property in your Activity?
I see you are using the OOTB function @Default.Base64Decode on the original (base64/text) data held in the 'pyAttachStream'.
Personally: I have never got that function to work in this way; it returns a String from a String (right?).
I have tended instead to use a Java Step to hold the resultant decoded b64 data in a Java Array.
I'm not saying my approach is 'more correct' - its just that I happened to get it working that way.
Take a look at this Post:
https://community1.pega.com/community/product-support/question/zip-binary-file-and-word-file-and-downloading-zipped-file
And in particular the Java Steps in there; you should be able to re-arrange this to suit your needs.
Can you give this a go and see whether you can get it working?
If you can't get it working - please post up your Activity you tried (include Steps, Pages and Params tabs) - and expand any steps.
(For Java Steps; just copy the Java inline - easier to see).
Thanks
