I'm unable to delete multiple foldes on mac the mac os finder. It says the file is write protected, even though the files all have the same permissions. On windows i am able to handle the files totaly fine.

While doing a fix common problems check, i get these errors, which corrosponds with the folders im unable to delete on mac os Finder:

 

How would i be able to delete all of these ":" characters from the folders without messing anything up?

Also how can i remove whitespace at either the beginning or the end of the file names?

If you can access them fine via Windows, I'd try that first.  After that try Krusader.  Failing that, mc at the command prompt.  Manual process unless someone comes up with a nice little bash script for you to handle it all.
