update file paths easyli?

[Studio Smalbro]

I have a bunch of FrameMaker 7 book files which I need to move from a
network drive to a local drive. This means that all file paths which reads
for instance "Y:manual/version01/manual.fm" now has to be updated to a new
file path which might read as: "C:Manuals/new/manual.fm". I can solve this
by converting the book files to mif and use a text editor to search and
replace text strings, but it is enormously cumbersome. There has to be an
easier way - but how? Can anybody help?

Best regards
Bjørn
