Generic rules for raster image files is there will be at least two or
three files for each tile:
* The raster itself
* The world file which has a similar extension usually ending with a W
e.g. JGW for a JPEG tile
* One or more XML files
The world file contains the coordinates and pixel size information, the
XML file(s) will contain the CRS information.
If these files are missing Qgis will display a ? at the end of the file
name when attempting to load it.
You can set the CRS in Qgis to compensate for a missing XML file CRS,
but the world file is essential otherwise the raster will be loaded at
the origin coordinates (0,0) of whatever CRS is being used.

Hi, I used QGIS about 4 years ago to produce maps for 1:25,000 and
1:50,000 OS maps, I feel a fool now, but I am struggling to get QGIS
2.18.28 to upload the files in the Raster (miscellaneous) section as I
used to do. I just get all the files not being recognised.
I have downloaded the latest QGIS 3.8, but do not understand this one
at all.
Could someone help me with a step by step loading of the OS raster
data into the QGIS system so that I can produce some maps please?
I also have the Geo referencing and sea tiles but again QGIS does not
seem to like them. I am using EPSG:27700
Thank You
Derek
