I have made a copy of a lot of picture files from an iPhoto directory from an Mac and when I do this i got a lot of preview files with me. The preview files is named ._IMG_Filename.jpg.
I took an search for all the preview with the find command in dopus. As the picture shows it is 12707 items found. Almost all of the files have the size 4 KB. When I am selecting all the files and delete the files I get an comfirm request windows that ask me if I want to delete 12707 files and 2 294 032 TB from the disk.
The number of TB is too high. If we take 4KB * 12707 I only get 50828 KB which is the real size of the files.
I have an Rar file with all the files and it takes about 9.29 MB and I can send it if needed.
