Re: [Qgis-user] Is there a limit of loaded files in QGis 1.8 ?
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].

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?

You checked use estimated metadata in 1.7, but apparently not in 1.8.
Also QGIS 1.7 offered the possibility to already open a schema while
still detecting. The type said waiting for the views in question but
you could nevertheless load a layer where the geometry type was already
detected (e.g. because it is registered in geometry_columns).
The detection is now done in a thread, so you can cancel the detection.

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.
