"recursive is limited to 400,000" ? Is that 400,000 files, or folders, or ??
The File Walker link (i.e.
http://www.sonsothunder.com/devres/livecode/tips/file007.htm ) should
work - it would be very interesting to find out why it doesn't (maybe
URL encoding of the file names??)
However, it too is recursive. Here's a non-recursive version of it,
which is somewhat faster in some cases: (be careful testing this - you
need to run it repeatedly to avoid file-system caching effects).
on dirWalk whatFolder
local temp, tCount, tDirList, tDirsToDo
set the itemDel to "/"
set the directory to whatFolder
put whatfolder &CR into tDirsToDo
repeat forever
put line 1 of tDirsToDo into whatFolder
set the directory to whatFolder
delete line 1 of tDirsToDo
put the files into temp
add the number of lines of temp to tCount
sort temp
repeat for each line x in temp
put whatFolder & "/" & x & cr after gHierList
end repeat
put the folders into tDirList
sort tDirList
delete line 1 of tDirList
repeat for each line x in tDirList
put whatFolder & "/" & x & CR after tDirsToDo
end repeat
if the number of lines in tDirsToDo = 0 then exit repeat
end repeat
end dirWalk

Here is a link for a file and folder lister

It appears recursive is limited to 400,000.
As for the File Walker link I tried it in one of
my folders that has a lot of files and subfolders
and it did not work for me but it did in other
folders.
If you get one that works please post it.

Hi all.
I remember reading in a post that someone had made a stack that would walk through a
file folder and enumerate all the files and folders. I cannot for the life of me find
it in the Livecode Share site or the forums. I cannot search for “list files” or
“find all files” because the forum search complains the words I am searching for are
too simple! <GAAAHHH!>
I have written a command to do it and it works up through the files in the
first folder it finds, but when it comes to going back to a prior recursion it
does not seem to work. Here is the handler:
on enumerateFilesAndFolders theCurrentPath, @theCurrentList
set the defaultFolder to theCurrentPath
put the files into theCurrentFileList
put the folders into theCurrentFolderList
put theCurrentFileList & theCurrentFolderList into theCurrentFilesAndFolders
filter theCurrentFilesAndFolders without ".*"
sort theCurrentFilesAndFolders Ascending
repeat for each line theCurrentLine in theCurrentFilesAndFolders
put theCurrentPath & "/" & theCurrentLine into thePath
if there is a file thePath then
put thePath & cr after theCurrentList
else if there is a folder thePath then
put thePath & “/“ & cr after theCurrentList
put thePath into theCurrentPath
enumerateFilesAndFolders theCurrentPath, theCurrentList
end if
end repeat
end enumerateFilesAndFolders
It seems after the recent iteration is finished, the value of theCurrentPath is
not reverting to the version of the prior iteration instance. In other words,
it seems to be global to all instances of the iterations of the handler. I was
under the distinct impression that each iteration had it’s own copies of a
given variable because of the implicit scoping used by Livecode. Apparently I
am mistaken.
I would like to see how anyone else has done a file walker.
