check for File

[Tigerweld]

Trying to check for file exists, but for some reason it isn't working and I think it may be something to do with Windows 7 permissions?  Anyone else run into this problem?  I get File does not exist no matter what.

If FileExists ("c:\windows\system32\test.txt") Then
    MsgBox(4096, "Yes", "File does exist")
Else
    MsgBox(4096, "No", "File does not exist")
EndIf

#RequireAdmin
If FileExists(@WindowsDir & "\System32\test.txt") Then
    MsgBox(4096, "Yes", "File does exist")
Else
    MsgBox(4096, "No", "File does not exist")
EndIf

Add this line to the top of your script

#RequireAdmin

 

[Tigerweld]

still comes back as "file does not exist"

Are you running on a X64 windows version and running with autoIt3 x86?

then do try to compile again

[Tigerweld]

compiling it as x64 did the trick!  thanks.  Will this script work on a x86 computer?

[youtuber]

no for x86

FileExists(@SystemDir & "\test.txt")

From the docs:

Running the 32-bit version of AutoIt on a x64 System

For Files, Windows has a special redirection mechanism for some system directories :

Directories	32-bit Value	64-bit Value
@SystemDir	@WindowsDir & "\System32"	@WindowsDir & "\SYSWOW64"
@ProgramFilesDir	{SystemDrive} & "\Program Files (x86)"	{SystemDrive} & "\Program Files"

It's possible to access the 64-bit version of those directories by disabling the redirection mechanism.

#include <WinAPIFiles.au3>

_WinAPI_Wow64EnableWow64FsRedirection(True)

Additional information can be found at MSDN.

For registry interaction, use HKCR64 or HKLM64 to bypass the redirection mechanism see Registry Functions documentation.
