xcode4 - XCode 4: fixing red source files in the project navigator -

in xcode project, of source files show in reddish in navigator. double clicking on them not open them in text editor.

the file paths right in file inspector, though, , project compiles well.

it's if compiler part of xcode can find files, text editor part can't.

can suggest how might prepare project can open source files in editor?

curiously, i've tried deleting , re-adding them, doesn't seem work. file names still show in red.

any ideas?

here similar happened me in git may help. if had changed directory path of files 1 of folders in path have "/" in name, cause files turn reddish , inaccessible.

hope it.
