Que tal.
Estoy realizando un codigo que mantenga limitado el tamano de un directorio. Para ello necesito saber cual es el tamano de un directorio y como saber la fecha de creación de un archivo. La idea es limitar el tamano del directorio borrando los mas viejos.

Saludos... :hola:
RYAN

:hola:

Aca les coloco lo que he podido encontrar para la realización del proyecto de control de tamano de un directorio.




Public Const MAX_PATH = 260

dwLowDateTime As Long
dwHighDateTime As Long
End Type

ftLastAccessTime As FILETIME
ftLastWriteTime As FILETIME
nFileSizeHigh As Long
nFileSizeLow As Long
dwReserved0 As Long
dwReserved1 As Long
cFileName As String * MAX_PATH
cAlternate As String * 14
End Type

lpFindFileData As WIN32_FIND_DATA) As Long
Declare Function FindClose Lib "kernel32" _
(ByVal hFindFile As Long) As Long
