Looks like FileCopy copies extra files under certain circumstances.

Here's an example:

Run this in CodeBox:

FileCopy,"D:\TestInput\testfile.*","D:\TestOutput"

with the content of D:\TestInput being:

d:

cd TestInput

dir /s *

Volume in drive D is WORK

Volume Serial Number is 40C5-6EEB



Directory of D:\TestInput



10/15/2009  01&#58;44 PM	<DIR>		  .

10/15/2009  01&#58;44 PM	<DIR>		  ..

10/15/2009  01&#58;30 PM	<DIR>		  junk

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes



Directory of D&#58;\TestInput\junk



10/15/2009  01&#58;30 PM	<DIR>		  .

10/15/2009  01&#58;30 PM	<DIR>		  ..

10/15/2009  01&#58;30 PM	<DIR>		  junk

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes



Directory of D&#58;\TestInput\junk\junk



10/15/2009  01&#58;30 PM	<DIR>		  .

10/15/2009  01&#58;30 PM	<DIR>		  ..

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes



	 Total Files Listed&#58;

			   3 File&#40;s&#41;			  0 bytes

			   8 Dir&#40;s&#41;   1,742,062,592 bytes free

You will get the output (with both 77RC2 and 78SP2):

d&#58;

cd TestOutput

dir /s *

Volume in drive D is WORK

Volume Serial Number is 40C5-6EEB

 

Directory of D&#58;\TestOutput



10/15/2009  01&#58;44 PM	<DIR>		  .

10/15/2009  01&#58;44 PM	<DIR>		  ..

10/15/2009  01&#58;43 PM	<DIR>		  junk

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes

 

Directory of D&#58;\TestOutput\junk



10/15/2009  01&#58;43 PM	<DIR>		  .

10/15/2009  01&#58;43 PM	<DIR>		  ..

10/15/2009  01&#58;43 PM	<DIR>		  junk

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes

 

Directory of D&#58;\TestOutput\junk\junk



10/15/2009  01&#58;43 PM	<DIR>		  .

10/15/2009  01&#58;43 PM	<DIR>		  ..

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes



	 Total Files Listed&#58;

			   3 File&#40;s&#41;			  0 bytes

			   8 Dir&#40;s&#41;   1,742,061,568 bytes free

whereas, I would have expected to see ONLY ONE (testfile.txt) file in D:\TestOutput.

FileCopy seems to be copying all files that match the filename within subdirectories also - seems to be something to do with the use of '*'.

Thanks.

They ARE the same.

Point is if that should be the effect of the command:
FileCopy,&#34;D&#58;\TestInput\testfile.*&#34;,&#34;D&#58;\TestOutput&#34;

what oriensol expected was a result like this:

d&#58;

cd TestOutput

dir /s *

Volume in drive D is WORK

Volume Serial Number is 40C5-6EEB



Directory of D&#58;\TestOutput



10/15/2009  01&#58;44 PM	<DIR>		  .

10/15/2009  01&#58;44 PM	<DIR>		  ..

10/15/2009  01&#58;29 PM				 0 testfile.txt

			   1 File&#40;s&#41;			  0 bytes
WITHOUT the creation of the /junk and /junk/junk subdirectories AND files in them.

I guess you should use
FileCopy,&#34;D&#58;\TestInput\testfile.*&#34;,&#34;D&#58;\TestOutput&#34;,NOREC

FileCopy seems to be copying all files that match the filename within subdirectories also - seems to be something to do with the use of '*'.

for backward compatibility wildcards copy recursive

Thanks Lancelot. I wasn't aware of the functionality - did not seem obvious.
