Offline pbi install?
arrowdodger is correct.
The AppCafe does not currently keep the downloaded PBI files after it installs them. In order to keep the actual PBI you will need to run "pbi_add -R (pbi-name)" from the command line. Alternatively, you can re-package an installed PBI back into the .pbi file by using the command "pbi_create -b (pbi-name)".
We will be adding the ability for AppCafe to save .pbi files probably in time for PCBSD 9.1
