Checking For Write Access On Folders

[objectivescott]

I need to have my script check a folder to ensure it is writable before the script attempts to write data files there. Does anyone have a good way of doing this already?

Up to this point, I've been using the FileOpen code and getting its return value of

-1 if the folder is not writable. The problem with this is, the script must create a file there first in order to give me this answer. I would like a clean way of checking a folder for writablility.

Any thoughts?

Can't you just erase the file after words?

;Folder Write-Protection Checking example by AutoElectric
$Folder = TheFolder

$Protected = 1
$Handle = FileOpen($Folder&\Test,2)

If $Handle <> -1 then
     FileDelete($Folder&\Test)
     $Protected = 0
EndIf

I don't see any other solution.

Maybe there is a command line tool that will check it but it is not of my knowledge.

Edit: Appearantly the forum does not allow font styles to be embedded within code tags.

Yes it's called 'attrib'

Would just manually setting the folder to writeable work?

RunWait(@ComSpec & ' /c attrib -R',@DirectoryYouWantToCheck,@SW_HIDE)

The Autoit inbuilt functions maybe more suited, to the task?

FileGetAttrib ( "filename" )
FileSetAttrib ( "file pattern", "+-RASHNOT" [, recurse] )

Thanks guys. The thing is...the folder may not even be available. For example, the folder may reside on a server which is currently offline or unavailable. Attrib will not work for this. That is why I was careful to say "writable"...as opposed to "have write permissions".

Creating a file and then deleting it afterwards is a little silly and unclean I think.

I'm not following. If you are able to create a folder on a computer you are absolutely able to check the attributes of folders on that computer as well...

Edit: able to create a file

I thought it was attrib, but I didn't seem to see the relation ship between non-writtable and read only. I thaught write-protected folders were set by some other means.
