Number of files in a folder?

[Seymour Clufley]

This is a ridiculously basic question and I'm sorry to ask it.

Is there a fast way to get the number of files in a directory, on Windows?

I had a look in PureArea and found this but that simply loops through all the files with NextDirectoryEntry. Surely there's an API call or something which can get the number more quickly than that?

It doesn't need to check sub-directories.

There is no other way, at least not as far as I know.
You have to iterate through the directory to count the files.

The main reason for that being the file system's access management.
In that folder there might be some files you're not allowed to see, so the operating system
has to check your access rights for every file.

For this kind of thing I usually use a script but you can still drive the action from PB.

Actually, that's pretty fast (once you delete the recursion into subfolders of it).

Or maybe populate an (invisible) ExplorerListGadget() with your path and count its files:

Code: Select all

If OpenWindow(0,0,0,400,400,"",#PB_Window_SystemMenu)
  ExplorerListGadget(0,0,0,400,400,"C:\Windows\",#PB_Explorer_NoFolders)
  SetWindowTitle(0,Str(CountGadgetItems(0)-1))
  Repeat : Until WaitWindowEvent()=#PB_Event_CloseWindow
EndIf
