tcl script and absolute file locations

I use Altium and I have the following script for including a mega function,

set_global_assignment -name QIP_FILE FIR_LP.qip

the problem is that I have to place all the mega function generated files in the project directory. Can I add an absolute path e.g. C:\mega\FIR_LP.qip and does this mean Quartus will then search this directory for the mega function library. If so what is the exact syntax?

    Most megafunctions create .qip files with relative paths. For example, if I do a PLL, the .qip has the following line in it:

    set_global_assignment -name VERILOG_FILE [file join $::quartus(qip_path) "mypll.v"]

    So $::quartus(qip_path) is a variable on where the .qip file is, and mypll.v is then relative to that.

    And you should be able to do exact paths:

    set_global_assignment -name QIP_FILE "C:/mega/FIR_LP.qip"
