I have been searching the web and have failed to find any reference to a problem I have with my computer. It appears that my files are being zipped by a program working the background. The zip files have the name of the file and an extension ._sa. for example cv.docx has been zipped into cv.docx_sa. When I attempt to open the file I a password dialogue appears. I have tried a number of password without sucess. Any ideas??
