Batch convertion problem tif + cal --> pdf

[Newbie]

Hi there!

I'm all new to the software. I have a relatively large tree structure with about 5.000 files. There are jpg, tif, cal and dwg. I want to convert them to pdf. (If it's possible I would like to exclude the dwg-files, but that i secondary.)

When I use the batch convert function I get to choose which folders to include. It works very well, except the problem that it does not catch the cal-files. All the other file types are converted. Any idea of what I can do to catch them in the selection?

cal from which software?

I actually have no idea. The files are from 2003.

They can be read as an image when I open them i xnview.

Here's a link to one of the files, I hope it works.

If you're starting out afresh, you would possibly be better using the current XnView MP software, or if you only need batch conversion, the very neat standalone XnConvert batch conversion software.

At a quick look, I think you may be able on the Input tab to select only selected file types if you can use use Add files..., not sure if you use Add folder..., something you can explore that might be useful.
