 |
|
Ever wonder how many contents are contained in a given folder on PSP?
Here is how...
| Code: | files = System.listDirectory "pathname"
-- files is a list of all files and subdirs in the pathname
local ndirs = 0
local nfiles = 0
for i = 1, table.getn(files) do
if files[i].directory then
ndirs = ndirs + 1
else
nfiles = nfiles + 1
end
end
print("# of subdirs found in the list", ndirs)
print("# of files found in the list", nfiles)
|
Warning: Don't run the script on Windows. The current version does not support System.listDirectory() yet.
Have fun!

I haven't included some folders in the folder for testing but I believe they are counted as well.
Thanks for asking.

No, they are not counted, listDirectory is the same like the DOS "dir" command or the Unix "ls" command (without any switches). But it is easy to count all files and directories in a directory and all subdirectories:
| Code: |
function countFiles(directory)
local flist = System.listDirectory(directory)
local filesCount = 0
local directoriesCount = 0
for index, file in flist do
if file.name ~= "." and file.name ~= ".." then
if file.directory then
local subdir = directory
if string.sub(subdir, -1) ~= "/" then
subdir = subdir .. "/"
end
subdir = subdir .. file.name
newFiles, newDirectories = countFiles(subdir)
filesCount = filesCount + newFiles
directoriesCount = directoriesCount + newDirectories + 1
else
filesCount = filesCount + 1
end
end
end
return filesCount, directoriesCount
end
files, directories = countFiles(System.currentDirectory())
print("current directory: files: " .. files .. ", directories: " .. directories)
files, directories = countFiles("ms0:/")
print("memory stick: files: " .. files .. ", directories: " .. directories)

I tested the code (after being editted) in the first post and found out that table.getn(files) counts every files and subdirs in a SINGLE folder.
Sorry, dude. I should have said "contents" instead of "files" in the title.
