windows - Batch - Moving file up a level if it's the only file in the directory -

i have several hundred folders. of folders have 1 file in them. if folder contains 1 file, i'd move file directory, it's parent file, , delete empty folder. hope i'm making question clear. i'm assuming best way this, batch file? i'm on windows.

- root directory    - folder 1       - file 1*    - folder 2       - file 1       - file 2    - folder 3       - file 1*    - folder 4       - file 1       - file 2       - file 3 

i'd files asterisks moved root directory.

this should out. few notes it's doing.

• the first loop walks directory tree current directory
• the second loop counts files (no directories), if there 1 file moved parent directory
• the 3rd loop counts both files , subdirectories, , tries removing if empty

you should find running multiple times move single file multiple levels of directory tree - if it's file @ each level.
