Hi, while hacking together an --output-dir option for mkgmap, I stumbled over a bug: Dirent.java in package uk.me.parabola.imgfmt.sys Change indexOf() to lastIndexOf() in line 76 of Dirent.java. The file extension is always to be searched for after the last dot. As a side effect, this now allows names like clas.de.TYP for style files. All the best, /Markus
