When I type magick -quality 100% -density 72 myimage.pdf myimage.jpg strange files with tens of MB size are created in C:\Documents and Settings\Coulon\Local Settings\Temp e.g. magick-3372SqB0j-S-pBcL1 size 29 MB. What are they here for? They are not automatically deleted when the conversion has finished.

These are temporary files, either the input PDF passed to Ghostscript, or raster images created by GS passed back to IM.

IM should automatically delete the images after processing. If there is a major problem that crashes IM, it won't delete them.

You can manually delete the files whenever IM isn't running, eg as part of your shutdown or startup process. It is good housekeeping to regularly delete files in %TEMP%.

Thanks. Some of them have have the "read only" attribute and I have to change this with ATTRIB -R <stuff>.

If you can't delete them manually, then IM will have the same problem. There may be a setting on the directory that makes created files read-only.
