Opening files Error -36 I am trying to open files on Time Capsule (not backups) but files will not open in Finder.  I'm receiving error -36.  When I copy files to my MacBook Pro, files opened without any problems. Quick Look works fine on Time Capsule.

Can anyone please help?
I had this problem recently and it was due to a problem with the previous version of macOS Sierra supported by acknowledgement by Apple of many similar reported bug in version 10.12.2.

The most recent update to macOS Sierra 10.12.3 resolved the error -36 with previewing files on the Time Capsule for me, try updating. 

Dot_clean did not work for me but connecting the TC via SMB was a simple workaround until Apple sorted the issue out.
