The process is executed on the condition of the UPLOAD button being pressed.

Apex 4.2 : I want to capture the filepath after browsing and selecting a file using item File browse (WWV_FLOW_FILES). The file is uploaded as a BLOB but all info regarding its original location is missing, as it is replaced by f.i. F12457/.docx. When using File Browse (browsing for a document and selecting) however the complete path (f.i. L:abcdefdocument.docx) is shown in the field (although its value than is already F999999/document.docx).
