I get a DirectoryIsNotEmpty exception on FileReference(AbstractFileReference)>>deleteAll. But deleteAll is supposed to delete children too. -> So why the exception ? I can reproduce it with: --- | sourceFolder deleteMeFolder numberOfRetries | sourceFolder := '/network-drive-mounted-via-cifs/delme-tmpl/'. deleteMeFolder := '/network-drive-mounted-via-cifs/delme/'. "copy sourceFolder to deleteMeFolder:" sourceFolder asFileReference copyAllTo: deleteMeFolder asFileReference . "delete deleteMeFolder again:" numberOfRetries := 0. [    deleteMeFolder asFileReference deleteAll ] on: DirectoryIsNotEmpty do: [:ex|     (numberOfRetries := numberOfRetries + 1) < 5         ifTrue: [ ex retry ]    ]. Transcript crLog . Transcript show: 'Retries: ', numberOfRetries asString . --- ---> numberOfRetries is now = 1 ! BUT: this only happens when sourceFolder and deleteMeFolder are on a network drive mounted via cifs. (linux fstab entry like: //host/share /network-drive-mounted-via-cifs/ cifs credentials=...,uid=... 0 0 ) How do I handle such situations when working with the file library on network drives? (My "retry on exception" workaround seems hackish to me.) Thanks, Albrecht
