I'm using the command:
C:\Users\CTStudent\Downloads>move *.pdf C:\pdfs
in order to move all the pdf files in my current directory to the pdfs directory. I was able to accomplish this MOVING 1 file:
C:\Users\CTStudent\Downloads>move CramSheet.pdf C:\Users\CTStudent\Downloads\pdfs
but for some reason when I use the wildcard it doesn't work. What am I doing wrong?I don't see anything wrong with your command, that should work for multiple files, even if they have long file names

what is the output of the move command? is there an error message?it's *.* to move all...
TRY that*.* specifies all files, whatever the extension. To specify all files of a particular extension, use an asterisk, a dot, and the extension, for example *.pdf.

So the command should work, if you typed it CORRECTLY, unless (for example) there are no PDF files in the source folder, or you do not have write permissions to the target folder, or it does not exist, or the files are in use, or a number of other things. If there was such an error, you should see an error message, but you just say it 'doesn't work'. That is the bane of HELP forums, and on Stack Exchange might get the question closed for 'lack of information'.
