Extract full path from string

Recommended Posts

I've read several threads here regarding identifying/capturing special-purpose file paths or subcomponents, but I'm afraid I still haven't figured out how best to extract a full file path from a string, such that the result either includes existing quoatation marks or adds them if necessary due to embedded spaces. I'm just not getting it. I don't think I'll need to validate the path, with the exception of the quote marks., but someone might. They might be in UNC format. They will all have extensions, so there's no need to worry about names without them. I guess this will need a regular expression?

Thank you for your help.

Here is a UDF I wrote for work purposes which may help:

#include-once

#include <Array.au3>
#include <File.au3>

Global $g_sScitePath = RegRead("HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Scite.exe", "")
    If @error Then $g_sScitePath = _FullPath(@AutoItExe, True, True, False) & "Scite\Scite.exe"

ConsoleWrite(";~ Example 1 : Return Scite file path, with quotes if folder path has any whitespace." & @CRLF)
ConsoleWrite(";~ Result  1 : " & _FullPath("'" & $g_sScitePath & "'", Default, False, False) & @CRLF & @CRLF)

ConsoleWrite(";~ Example 2 : Return Scite folder path down one PARENT level, with trailing backslash and without quotes." & @CRLF)
ConsoleWrite(";~ Result  2 : " & _FullPath("'" & $g_sScitePath & "'", False, True, True, -1) & @CRLF & @CRLF)

ConsoleWrite(";~ Example 3 : Return Scite folder path up one ROOT level, with trailing backslash, enclosed in quotes" & _
             ";~ (uses single quote detemined by $_sFullPath quotes)." & @CRLF)
ConsoleWrite(";~ Result  3 : " & _FullPath("'" & $g_sScitePath & "'", True, True, True, 1) & @CRLF & @CRLF)

ConsoleWrite(";~ Example 4 : Return 3rd level ROOT folder Path with trailing backslash, not enclosed in quotes" & @CRLF)
ConsoleWrite(";~ Result  4 : " & _FullPath("C:\Users\Michael O'Brien\AppData\Roaming\Documents\Filename.doc", False, True, True, 3) & @CRLF)
ConsoleWrite(";~ Full Path : " & _FullPath("'C:\Users\Michael O'Brien\AppData\Roaming\Documents\Filename.doc'", False, True, False) & @CRLF & @CRLF)

ConsoleWrite(";~ Example 5 : Return 3rd level PARENT folder without trailing backslash, enclosed in quotes" & _
             ";~ (enclosed in double quotes, since folder includes single quote)." & @CRLF)
ConsoleWrite(";~ Result  5 : " & _FullPath("'C:\Users\Michael O'Brien\AppData\Roaming\Documents\Filename.doc'", True, True, False, -3) & @CRLF)
