(C) Iterate over Files and Directories in Filesystem Directory TreeDemonstrates how to use the Chilkat DirTree object/class to iterate over the names of files and sub-directories in a directory tree. This example iterates over a directory tree that contains these files and sub-directories: a images (sub-directory) dudeA.gif Thumbs.db hamlet.xml pigs.xml Setup.exe b yyy (sub-directory) zzz (sub-directory) HelloWorld123.txt test123.txt dude.gif dudeC.gif hello.txt Thumbs.db test123.txtThe output for the code below looks like this: (sub-directory) Relative Path: a Absolute Path: c:\temp\abc123\a Absolute UNC Path: \\?\c:\temp\abc123\a ---- (sub-directory) Relative Path: b Absolute Path: c:\temp\abc123\b Absolute UNC Path: \\?\c:\temp\abc123\b ---- Size in bytes: 15 Relative Path: test123.txt Absolute Path: c:\temp\abc123\test123.txt Absolute UNC Path: \\?\c:\temp\abc123\test123.txt ---- Size in bytes: 279658 Relative Path: a\hamlet.xml Absolute Path: c:\temp\abc123\a\hamlet.xml Absolute UNC Path: \\?\c:\temp\abc123\a\hamlet.xml ---- (sub-directory) Relative Path: a\images Absolute Path: c:\temp\abc123\a\images Absolute UNC Path: \\?\c:\temp\abc123\a\images ---- Size in bytes: 8463 Relative Path: a\pigs.xml Absolute Path: c:\temp\abc123\a\pigs.xml Absolute UNC Path: \\?\c:\temp\abc123\a\pigs.xml ---- Size in bytes: 24576 Relative Path: a\Setup.exe Absolute Path: c:\temp\abc123\a\Setup.exe Absolute UNC Path: \\?\c:\temp\abc123\a\Setup.exe ---- Size in bytes: 6221 Relative Path: b\dude.gif Absolute Path: c:\temp\abc123\b\dude.gif Absolute UNC Path: \\?\c:\temp\abc123\b\dude.gif ---- Size in bytes: 6221 Relative Path: b\dudeC.gif Absolute Path: c:\temp\abc123\b\dudeC.gif Absolute UNC Path: \\?\c:\temp\abc123\b\dudeC.gif ---- Size in bytes: 13 Relative Path: b\hello.txt Absolute Path: c:\temp\abc123\b\hello.txt Absolute UNC Path: \\?\c:\temp\abc123\b\hello.txt ---- Size in bytes: 10240 Relative Path: b\Thumbs.db Absolute Path: c:\temp\abc123\b\Thumbs.db Absolute UNC Path: \\?\c:\temp\abc123\b\Thumbs.db ---- (sub-directory) Relative Path: b\yyy Absolute Path: c:\temp\abc123\b\yyy Absolute UNC Path: \\?\c:\temp\abc123\b\yyy ---- (sub-directory) Relative Path: b\zzz Absolute Path: c:\temp\abc123\b\zzz Absolute UNC Path: \\?\c:\temp\abc123\b\zzz ---- Size in bytes: 6221 Relative Path: a\images\dudeA.gif Absolute Path: c:\temp\abc123\a\images\dudeA.gif Absolute UNC Path: \\?\c:\temp\abc123\a\images\dudeA.gif ---- Size in bytes: 6144 Relative Path: a\images\Thumbs.db Absolute Path: c:\temp\abc123\a\images\Thumbs.db Absolute UNC Path: \\?\c:\temp\abc123\a\images\Thumbs.db ---- Size in bytes: 6080 Relative Path: b\zzz\HelloWorld123.txt Absolute Path: c:\temp\abc123\b\zzz\HelloWorld123.txt Absolute UNC Path: \\?\c:\temp\abc123\b\zzz\HelloWorld123.txt ---- Size in bytes: 15 Relative Path: b\zzz\test123.txt Absolute Path: c:\temp\abc123\b\zzz\test123.txt Absolute UNC Path: \\?\c:\temp\abc123\b\zzz\test123.txt ----
