Profound Logic Forums

I am using the upload widget to load files to a directory /Documents/temp
The user will click a button or enter which will turn on an indicator (btnUpload)
Profound processes the exit program immediately -
My processing renames the uploaded file by appending the custno to the name of the file, checking for duplicates in /Documents and renaming with (#) appended if necessary - Is there any built in ways to doing this that I have not found?

Ideally I would like to rename it before the exit program is run
I know I can use the rename property but it seems that name would have to be determined before I even selected a file
I have the custno on the screen before I select a file for upload
Is there a way to do this (set a new rename value as soon as the file is selected ie. bound Rename Variable = custNo + fileName ?

Thanks!
