Android Question File.Exists Issue

[David Hawkins]

Hi

I appear to be getting a strange result with file.exists. If the file exists then all is OK but if the file does not exist it is created by the file.exists function. My question is, should that happen.

I have checked and double checked to make sure that the case sensitivity is correct but the issue is still there.

Regards

That doesn't sound right, the File.Exists just checks for well, the existence of the file or not, it doesn't create anything.

Can you post the relevant code?

The function File.Exists does not create any files.

So your code creates the file.

Can you post that part?

Hi guys thank you for your fast response code is below

    If File.Exists(File.DirRootExternal & "/RWW/", DownloadedDBname) = True Then
        File.Copy(File.DirRootExternal & "/RWW/", DownloadedDBname, File.DirRootExternal & "/RWW/", Main.DatabaseName)
        File.Copy(File.DirRootExternal & "/RWW/", DownloadedDBname.ToUpperCase, File.DirRootExternal & "/RWW/", "BACKUP.DB")
        File.Delete(File.DirRootExternal & "/RWW/", DownloadedDBname)
    End If

It seems to me you might be copying or creating that file elsewhere.

Knock, knock ? Could it be because the path is artificially created and not created using File.Combine ?

    If File.Exists(File.DirRootExternal & "/RWW/", DownloadedDBname) = True Then
        File.Copy(File.DirRootExternal & "/RWW/", DownloadedDBname, File.DirRootExternal & "/RWW/", Main.DatabaseName)
        File.Copy(File.DirRootExternal & "/RWW/", DownloadedDBname.ToUpperCase, File.DirRootExternal & "/RWW/", "BACKUP.DB")
        File.Delete(File.DirRootExternal & "/RWW/", DownloadedDBname)
    End If

This code definitely does not create the file.

It is created elsewhere, such as NJDude wrote, or the file was previously created and not deleted. When you uninstall an app, files in the DirRootExternal are not automatically deleted.
