Number of files on a disk

[Natter]

Hi,

How do I know the total number of files on a disk ?

[ukoenig]

There is a freeware-tool

Foldersize 4.5.0.0

simply the best I know for the moment
it includes everything You need

https://www.techspot.com/downloads/6654 ... -size.html



Maybe You want to count only selected directorys
( could be counted from different drives )

Code: Select all  Expand view  RUN

STATIC FUNCTION READFOLD()
local nFiles  := 0
// Counting the main- and defined subdirectorys
local aSub     := { ".\", "BMP\", "PNG\", "JPG\" }
local I, cPath, aDir

FOR EACH I in aSub
      cPath     := I
      aDir      := Directory( cPath + "*.*" )
      AEval( aDir, { |a| nFiles++ } )
NEXT

MsgAlert( nFiles -= 1)

RETURN NIL

best regards
Uwe

Thank You, Uwe. I needed to make progressbar poll files on servers. I implemented this via diskused()

[ukoenig]

I will check it.

you will make a lot traffic if nothing have change ...

there is

Code: Select all  Expand view  RUN

HB_FUNC( WAITRUN )

in \fwh\source\winapi\winexec.c

it will wait until "something change" in a given Directory.
i have a Xbase++ Source using ot4xb*** for this.
