Over the years, as well as paper, as those who know me will agree, I have used more or less every method there is of transferring files from computer to computer: floppy disks of all kinds, CD-ROMs, DVD, Zip disks, removable hard drives of all shapes and sizes.
I now find myself with a problem. I have too many ways of doing it and I need to settle on one. So, I have several USB sticks, an iCloud account, Dropbox and Google docs, soon to become Google Drive, it tells me every time I use it. Though I'm supposed to be an information manager, the management element is somewhat lacking.
This becomes urgent. The other morning I found myself having to recreate a great deal of work because I didn't have the right file.
