Error 52: Bad File Name or Number Error

[Eneramo]

I want to check if a File name already exist. my code works perfectly when i tested it with a local path name. But the hole will be saved in a sharepoint and the Pathname will be given as an URL. It will be like this: FullFileName: https://sec-ishare.infineon.com/site...201611010.pptm
With a FullFileName like: C:\Users\... it works but with the other one i always get this error. (Bad File Name or Number)
this is my code:

OwnPathName = ActivePresentation.Path
FullFileName = OwnPathName & "\" & NewFileName
' for debug only (can remove it later)
'MsgBox OwnPathName
'MsgBox FullFileName
Dim StrFile As String
Dim FileFound As Boolean
FileFound = False
'look for all types of PowerPoint files only (filter only to PowerPoint files to save time)
StrFile = Dir(OwnPathName & "\*pptm*", vbHidden)
MsgBox StrFile
Do While Len(StrFile) > 0
If InStr(StrFile, NewFileName) > 0 Then
FileFound = True
Exit Do
End If
StrFile = Dir
Loop


can you help me please solving this problem?
Thanks in advance

The Dir() method does not work on URLs.

How can i solve the problem? any suggestion??

I can only think of trying to download the file, if it succeeds then the file is available.

There is many users and averything is in a sharepoint saved. that's the probleme :/

I don't understand what the problem is...

See StackOverflow: http://stackoverflow.com/questions/1...harepoint-site

I don't think he understands what "download the file" means.

or how it's fundamentally different from copying the file through the file system.

That StackOverflow link is about as simple as it gets.

Yes, but Dir() does only check if a file exists on a file system (or network share).
I'm not aware of an equivalent for checking if an URL exists, beside downloading the content.

Don't know what goal is of TS, just checking a single file, or building a list of available files.
