searching for a folder.

ENTHU

I have a code to accept folder name as input .Now I want to check if the folder exists in one of the 2 paths (pathA and PathB).

I was also able to achieve this but the challenge is,

I have many folders in these 2 paths and I dont know the name of these before-hand.

I tried using

filelist=Files In Directory( path1, recursive);

but this doesnt work for folders.

sure, approximately like this untested bit of JSL...

If( Is Directory( path || candidates[i] ),
   Write( "\!n", path || candidates[i] ); // <<<<<< do something with a dir
   descend( path || candidates[i] ); // optionally, recurse
, // else
   Write( "\!n", path || candidates[i] ); // <<<<<< do something with a file
)

You might need to use isFile(...) to make sure items are actually files and not other odd things the OS might show you.

Will this help you?

If( Directory Exists( "$SAMPLE_DATA/Loss Function Templates" ),
	"ok",
	"missing!"
);

Your code example uses the wrong syntax. Here is an example of the correct syntax:

Files In Directory( "$SAMPLE_DATA", Recursive( 1 ) );

The items in the list that is returned are full paths, so you can examine each one to find the target folders.

Craige_Hales

descend = Function( {path},
	{candidates, i},
	If( !Ends With( path, "/" ) & !Ends With( path, "\" ),
		path = path || "/"
	);
	candidates = Files In Directory( path ); // not recursive
	For( i = 1, i <= N Items( candidates ), i += 1,
		If( Is Directory( path || candidates[i] ),
			Write( "\!n", path || candidates[i] ); // <<<<<< do something
			descend( path || candidates[i] ); // optionally, recurse
		)
	);
);

descend( "c:\program files" );

If you don't want to explore sub directories, comment out the recursive line.

Can the code be amended to also include the file names as well as the folders?

thanks
