How can I edit my quartus project to work with relative paths?

I have a project in quartus with many files containing full-path-links to other files.

I found a way to make it work on my machine with a different location, but that is the cheat way.

I would like to change all the paths to be relative, so that other engineers won't have the same problems.

What should I do?

If I change all my "C:\projects\filt..." to relative "\filt..." will I ever get newly generated files with full paths when I continue working with it ?

And what should I do when i create a new quartus project (with nios hw and sw) to make full-path-links never appear anywhere?

For example the filt.elf file:

...filt_NIOSII_SW.c D:\filt\software\filt_NIOSII ...

For example the filt_NIOSII_SW.o file:

... alt_alarm_list D:\filt\software\filt_NIOSII_BSP alt_llist_insert...

For example the libhal_bsp.a file:

... filt_NIOSII_SW.c D:\filt\software\filt_NIOSII signed char ...
