I think you're confoozlicating yourself with all these oh-so-similar folder names.
I'm moving the contents of testy1 (a subdirectory within test1) to test1.
So when you're going from testy1 to test1, you're going from one directory to its parent directory, you're going up one level. (Look at what you wrote.)
This is what you have described as the relationship between the folders testy1 and test1
The command you said you used was this
move *.* ..\test\test1\
If executed from testy1, as you have written, the two dots take you up one level, to test1, then into a subdirectory of test1 called "test" (Huh?) then to a subdirectory of
that called test1.
That's different from what you said about testy1 being a subdirectory within test1!
I just tried it and this is what i got
I:\test1\testy1>move *.* ..\test\test1\
Cannot move multiple files to a single file.
I:\test1\testy1>
To move everything from a folder to the one directly above, which is what you said you want to do, you do this
move *.* ..
Like this
I:\test1\testy1>move *.* ..
I:\test1\testy1\image001.jpg
I:\test1\testy1\image002.jpg
I:\test1\testy1\image003.jpg
I:\test1\testy1\image004.jpg
I:\test1\testy1\image005.jpg
I just peeked and they are there, in test1.
