I don't know if there is an answer to this question, aside from the obvious.
I have about 30 different QGIS Project files for 30 different clients. Each is saved onto my computer and all their relevant vector and raster files are all saved locally.
We are now in the process of moving office and upgrading our computers.
As a result, I need to move all my files from my computer onto the network drive, thus destroying any previous file references.
Aside from manually clicking on each file and looking for each ones new location, is there any other way around this.
(Each project could have a few hundred links to update)
