Get String After Last '\' in File Address

[olympus]

How do I get the string after the last '\' in a file's address? Let's say the file is located in C:\Program Files\GreatSoftware\link.html. How do I obtain 'link.html' from the full address? I think I should use StringSplit but I'm not familiar with it.

Please help, thank you.

StringRegExpReplace($sPath, "^.*\\", "")

Or

_PathSplit()

Please see _PathSplit in the help file.

Function _PathSplitThere is also the useful

_PathSplit function which splits a path into the drive, directory, file name and file extension parts. An empty string is set if a part is missing.

and _PathMake function to put all the parts back together as a valid path.

How do I use _PathSplit? I referred to the help file and I didn't understand the example involving arrays... can someone make an example with a msgbox output? Thank you.

Yashied gave you the best solution but I'll turn it into an example

$sPath = "C:\Program Files\GreatSoftware\link.html"
$sFileName = StringRegExpReplace($sPath, "^.+\\(.*)$", $1)
MsgBox(0, "Result", $sfileName)

$sFileName = StringRegExpReplace($sPath, "^.+\\(.*)$", $1)

Thank you GEO for the example, but what are the meaning of the symbols in between the quotes and teh $1 at the end?

Take a look at the docs for StringRegExp for a description of what each part of a regular expression does. Let's see:

^ - beginning of string

. - any character

+ - previous character (group/set) one or more times

\\ - any actual \. Normally \ is used to escape special characters.

( - begin a capturing group. Contents from this group will go into $1

. - any character (again)

* - previous character (or group or set) zero or more times.

) - end capturing group.

$ - end of string.

Oh okok. I'll check it out. Thank you!

Hi olympus... that is regular expression string pattern... don't be afraid of that, you'll get used to it... you can also use string split, then take the last element...

$folder = FileSelectFolder("Select any folder","")  ;select folder, obviously

$path_array = StringSplit($folder,"\") ; Split path into an array element

$folder_name = $path_array[UBound($path_array)-1] ; take the last element

MsgBox(0,"",$folder_name) ; popup message box

Oh... now I get it, so when we're using the script below:

$sPath = "C:\Program Files\GreatSoftware\link.html"
StringRegExpReplace($sPath, "^.*\\", "")
MsgBox(0, "Result", $sfileName)

...we're telling it to replace all the characters(C:\Program Files\GreatSoftware\ = "^.*\\") before the file name with nothing(""), hence we are only left with the file name(link.html).

Thanks people, the examples were helpful.

Yupp, that's the idea... replace unwanted characters with empty string("") a.k.a delete them.. ;P
