How to get a list of subdirectories in the folder

[Eugene Lutsenko]

As the easiest way to get a list of subdirectories in a folder in an array.

As the easiest way to get a complete list of file names properly to type in subdirectories of a specified folder in an array.

As the easiest way to get a complete list of file names properly to type in subdirectories of a specified folder in an array.

that Question is too easy ...

use Directory() "recursive"

Code: Select all

PROCEDURE DirEval( cWorkPath, cMask, bBlock )
LOCAL aDIR
LOCAL nLEN
LOCAL nCount

   aDIR := DIRECTORY( cWorkPath + "*.*", "D" )

   nLEN := LEN( aDIR )
   FOR nCount := 1 TO nLEN
      IF "D" $ aDIR[ nCount, F_ATTR ] .AND. .NOT. ;
             ( aDIR[ nCount, F_NAME ] = "." .OR. ;
               aDIR[ nCount, F_NAME ] = ".." )

         DirEval( cWorkPath + aDIR[ nCount, F_NAME ] + "\", cMask, bBlock )
      ELSE
         EVAL( bBlock, cWorkPath, aDIR[ nCount, F_NAME ] )
      ENDIF
   NEXT

RETURN

The operative word is "specified".
This make it even simpler.

Try this:

aDir := Directory( 'C:\exp20\source\dclipx\*.prg')

In the end, I made stupid, but like works. I was surprised that the function: aAll: = DIRECTORY (cWorkPath + "*. *", 'D') provides information not only on directories, as expected, and all the files.

Code: Select all

   cWorkPath = M_ApplsPath+"\Inp_data\"
   
   aAll := DIRECTORY( cWorkPath + "*.*", 'D' )             // Почему-то в массив попадает информация не только по директориям

   IF LEN(aAll) = 0
      Mess = " В папке: "+cWorkPath+" нет файлов!"
      LB_Warning(Mess, "Оцифровка изображений по всем пикселям" )
      RETURN nil
   ENDIF

*  DC_DebugQout( aAll )

   aDir := {}

   FOR j = 1 TO LEN(aAll)
       IF aAll[j, 5] = "D"
       IF aAll[j, 5] <> '.'
       IF aAll[j, 5] <> '..'
          AADD(aDir, aAll[j, 1])
       ENDIF
       ENDIF
       ENDIF
   NEXT

*  DC_DebugQout( aDIR )

   aFileName := {}

   IF LEN(aDIR) = 0
      Mess = " В папке: "+cWorkPath+" нет поддиректорий!"
      LB_Warning(Mess, "Оцифровка изображений по всем пикселям" )
      RETURN nil
   ENDIF

   FOR j = 1 TO LEN(aDIR)
       aFNbmp = DIRECTORY( cWorkPath + aDIR[j] + "\*.bmp" )
       IF LEN(aFNbmp) > 0
          FOR f = 1 TO LEN(aFNbmp)
              AADD(aFileName, cWorkPath + aDIR[j] + "\" + aFNbmp[f,1] )
          NEXT
       ENDIF
       aFNjpg = DIRECTORY( cWorkPath + aDIR[j] + "\*.jpg" )

are you sure to get all Files

i have test your Code with my *.JPG / *.BMP and got 292 Picture with your Code and 374 Picture with my Code which is OK.

p.s. if you want to have "Size" of a Text try GraQueryTextBox()

I have not analyzed the subdirectories in the specified folder. I saw only one level of subdirectories in the specified folder. To me this is enough. And you have a recursive function and analyzes all levels of nesting. But I do not understand how it works. In particular, I do not understand what is:

  DirEval (cWorkPath + aDIR [nCount, F_NAME] + "\", cMask, bBlock)
       ELSE
          EVAL (bBlock, cWorkPath, aDIR [nCount, F_NAME])

and bBlock.

In general, everything was (earned). Later, as the show. There was the usual stupid mistake.

bBlock does contain what you want "todo" with each File

   IF UPPER(cMask) $ UPPER(ccFile)
      // only add Path and F_NAME
