Copy files without recreating subdirectories

问题

I have a directory that has about 100 subfolders and close to 2,000 files within those subfolders (up to 4 layers). The files are .txt or .log, and each extension has a unique file name. I need to move or copy (whichever is faster) the files to the root of a different folder without recreating the subfolder structure like xcopy does. This is on Windows xp

Thanks in advance.

Existing:

Dir1\Folder1\000111.txt
Dir1\Folder2\000112.txt
Dir1\Folder3\000113.log
Dir1\Folder4\Dir2\000114.txt
Dir1\Folder4\Dir2\000115.txt
Dir1\Folder4\Dir2\000116.log
Dir1\Folder5\Dir3\000117.log
Dir1\Folder5\Dir3\000118.txt
Dir1\Folder5\Dir3\Dir4\000119.txt
Dir1\Folder5\Dir3\Dir4\000120.txt
Dir1\Folder5\Dir3\Dir4\000120.log

Required:

Dir9\000111.txt
Dir9\000112.txt
Dir9\000113.log
Dir9\000114.txt
Dir9\000115.txt
Dir9\000116.log
Dir9\000117.log
Dir9\000118.txt
Dir9\000119.txt
Dir9\000120.txt
Dir9\000120.log

How about something like:

for /R %f in (*.txt,*.log) do copy %f dir9\%~nf

Issue this with dir1 as your working directory.

Have a read of for /? to understand why this works.

When I work on for statements I tend to try them out first like so:

for /R %f in (*.txt,*.log) do @echo copy %f dir9\%~nf
