Re: [Qgis-user] How-to-Batch_convert the Spatial resolution of a set of >100 Geotiff files from 500m to 1000m
Amal Kar akarcaz50 at gmail.com Tue May 31 12:37:20 PDT 2022 THANK YOU VERY MUCH, SIR! Hope the new version runs on my old Windows 7. Hi Amal Kar, QGIS 3.22 and QGIS 3.24 installed using the OSGeo4W installers (both network and standalone) are only available for 64 bit OS and don't support Windows 7 as you can read in the QGIS Website download page: "CAUTION: 32 bit binaries are not produced anymore. Also Windows 7 no longer works as we are now using Python 3.9, which dropped support for it." Anyway, the batch processing interface is available in any QGIS 3.x version. Best regards.

I'm pretty sure 3.18 had Batch processing - but I do concur with Nicolas - check and make sure that works on windows 7. Right click on that processing tool and see if you have a batch option.

It also helps if the output data file uses the same name as given for the input file, but allows the user to provide a short prefix to each of them (say 4-6 letters, either replacing the first 4-6 ones, or adding to the given names).

Depending on which version of QGIS you have (3.22, 3.24 - you can select the "translate" command in the processing toolbox (you'll find that under gdal -> raster conversion) and either right click the tool and run as batch process or in 3.24 you can select the batch button from the translate menu.
