Resume help

ok I'm not sure what was my job title for my last job and I'm not sure what to put on my resume. I have had already included other previous jobs with titles I already know. If this helps I worked in a small business that work with photography and my job was to file photos. So what can I put on my resume if I don't know the job title of my last job? I thought to put clerical assistant but I don't know.

call up the person that was your boss and ask them-or ask somebody that worked with you or knew what job you were doing

I think that title works: Clerical Assistant

You can also try : Administrative/Organizing Assistant
