I'm pretty sure you can do it in Toast, though I don't know much about it.
I do know that you can delete them using Terminal:
Open Applications->Utilities->Terminal.
In Terminal, type (but do not hit return!):
There is a space after 'cd' (i.e., so far, it's "cd ").
Drag the folder containing the files you don't want to the Terminal window and "drop" it - that'll add the path to your command (and won't actually move the folder), something like:
Code:
cd /Users/yourname/Desktop/TransferFolder
Obviously, the path will be different. Now hit 'return'.
That'll bring you into the offending folder. Now type (followed by 'return'):
That'll produce something vaguely like:
Code:
. Dummy.jpg
.. OSXTips.doc
.DS_Store
To get rid of the files you don't need - basically, anything with a filename starting with '.' (except for the directory indicators "." and ".."), meaning it's hidden, type the following (followed by 'return') for each of those files (I use .DS_Store as an example):
Now,
do not open the folder again using the GUI. Just copy it over. The hidden files will remain gone.
