Objective: I have point layers with attributes that contain paths to external files (Visio, AutoCAD dwg...). I want to put them all in one folder together with the project file, compress the folder into a ZIP file and send it to my colleagues for review. When my colleague de-compress the ZIP file, they would be able to open those files with simple actions like the posts linked below.
My observation: what I want to accomplish is very similar to those discussed in Adding a hotlink to an attribute field in QGIS and How to add links to PDFs in a Shapefile? with one difference: when the ZIP file is decompressed, the absolute path to referenced files will be different. But I think that RELATIVE PATHS to the project file will be the same, so why not use this?
The problem is: that I can not find a way to open external files with relative paths inside QGIS.
Any idea how to solve this problem?
