I have just looked, and I have client files from 2010 in my Google Drive and Dropbox folders! So, I would say the answer is indefinite.
On a serious note, I try to keep client files for about 12 months after the project ends or after I stop providing support as per the contract. However, all my web development files are already on GitHub, so I do not have to think about those.
