Re: [Qgis-user] Is there a limit of loaded files in QGis 1.8 ?
Hi Lorenzo, One thing that is worth a try is to use VRT files. See http://www.gdal.org/ogr/drv_vrt.html With a vrt file you can combine several files that have the same table structure to one virtual file. Maybe it is worth a try? I don't know if the same OS limitations apply then or not. The other option, as others have noted - is to use a database instead - which also opens other possibilities besides QGIS.

For those who want to try things out, in a Unix shell type: lsof -p 10371 where 10371 is the QGIS process id (so, adjust it). Each time you open a file, enter the same command and you'll see how many files QGIS is opening.

Hi, indeed, it is an operating system (OS) restriction. In my GNU/Linux the limit is 1024 by default, but you are able to change it. You would need to search how to change it on your OS. See [1].

Re: [Qgis-user] Is there a limit of loaded files in QGis 1.8 ?
Do you really need that bunch of files in one project? I am a cartographer, geologist and i work in minning too, and i deal with rasters (DEM's, LANDSAT IMAGES, EPIPOLAR, SCAN'S, ETC), vector (poligons, lines, points), DXF'S files and other, GPS files (*.gpx), wms services, databases, etc etc, and i have never load that many files in my projects.

[Qgis-user] Is there a limit of loaded files in QGis 1.8 ?
Hi all I have two big projects with many files, shape, geotiff and dxf files. In one project after loading the file number 64 it is impossible to load other files: I have always the error: "This file is not recognized". I have to delete some files and I can load other files. In another big project i have several hundreds small files. After the number 220 I have the error. I have to delete some files and I can load other files until the limit. This is a big problem because there are projects with many files and I don't know the limit of QGis. It is a memory limit, I think. Is it possible to fix this problem?
