You mean so you can know if you need to read ahead of your write?
Sub LogMessages(message As String)
' write active logs in temp
fileName = "tmp:/logmessages.txt"
LocalFileBrowser = CreateObject("roFileSystem")
text = ReadAsciiFile(fileName)
text = ""
You could probably do something like the above. Not sure entirely what you are after.
Here I tried to find a file path like a tree structure. In package storage, I created a one folder image and inside an image folder stored 1.txt file and I tried to find my file Location like a pkg:/images/1.txt using only file name 1.txt.
