Need help for R-Studio Mac version

Post by cyberjom » Tue Feb 17, 2009 5:06 am

many year ago I use R-Studio on my virtual machine under my MAC
but now the native mac coming out I have purchased it a few day ago.

But I can't recover any file from my 8G CF card which I have accidently quick format it by my Camara 5D MKII

Most of the file are Canon RAW 21 megapixel CR2 and 1 large HD video h.264 mp4 around 1-2GB

I have added FileTypes.xml but after restart it's show 5DMKII group but nothing in it.
After scan I found nothing usable. May I do something wrong ?

<?xml version="1.0" encoding="utf-8"?>
<FileTypeList>
<!-- Search for CANON CR2 -->
<FileType id="9001" group="5DMKII" description="Canon CR2">
<Signature offset="0" from="begin" count="1">\x49\x49\x2A\x00\x10\x00\x00\x00\x43\x52</Signature>
</FileType>

<!-- Search for CANON MP4 -->
<FileType id="9002" group="5DMKII" description="Canon MP4">
<Signature offset="0" from="begin" count="1">\x00\x00\x00\x18\x66\x74\x79\x70\x71\x74\x20\x20\x20\x07\x09\x00</Signature>
</FileType>
</FileTypeList>

I tested your descriptions and they appeared on the Known File Types list, although I did that on a Windows system. (I tested their presence, not the correctness of the file signatures.)
Tomorrow I will test that on a Mac system.
BTW, I think that Canon RAW 21 megapixel CR2 is already present on the Known File Types in the Graphic/Picture group. At least, on the Windows system.

The problem is that the attribute extension is missing.
The first line for CR2 should be:
<FileType id="9001" group="5DMKII" description="Canon CR2" extension="cr2">
the same attribute should be added for the Cannon MP4 files, too.
Actually, this attribute is optional, and therefore this is a bug.
