I use a great little (and free) backup program on my PC called GFI backup. Having now installed an N97-mini my usual backup fails as Nokia have installed a number of files i Documents and Settings with file path/names are >256 characters.
These are the files and it looks to me like I could justv delete them all but thought I'd ask those who undrestand these things better.
