Correct way to specify new file types

Post by Matteo » Sun Aug 19, 2018 12:59 pm

Thank you for your attention. The other day I was stupid enough to delete by mistake the partition of a disk member of a RAID0 configuration created under MacOs. The deletion happened under Windows 10 though.
R-Studio is able to recognize that two disks were formerly part of a RAID0, but a lot of files are missing. I have performed a scan, which helped only a little.
The file types that were stored are of a kind not been looking for by default by the software, so I find myself in the need of specifying them.
In details, I need to recover files made with 3d Software like Maya, ZBrush, Substance Painter and so on.
I have files on other disks that I have used to extrapolate the headers and the footers, then under R-Studio I created a new category called "3d Data" in which I have specified all the file types I need. For each of them, I added a signature "Begin" and signature "End", typing in the format \xNN the hex code I got from my files.
After performing the scan, however, in "Extra Found Files" the category I created is not present, and only the default ones are. Before starting the scansion, I did specify to look for my category as well.
Where is the mistake in my procedure?

Thank you for your help!

Sorry everybody, after the scansion, sorting the results by Extension, I was able to find my category and also the file types I specified.
So my question is solved, nevertheless if anybody feels to be able to contribute with some inputs concerning my situation, it would be very welcome!

I need to look through the code you created.

Here it is:

<?xml version="1.0" encoding="UTF-8"?>
<FileTypeList version="2.0">
<FileType id="50001" group="3d Data" description="Maya Binary" features="" extension="mb">
<Begin combine="AND">
<Signature>\x46\x4F\x52\x38\x00\x00\x00\x00</Signature>
</Begin>
<End combine="AND">
<Signature>\x7F\x00\x00\x00\x00\x00\x00\x00\x00\x00\x04\x00\x00\x00\x44\x00\x00\x00\x00</Signature>
</End>
</FileType>

</FileTypeList>

A small but important bug. The "offset" attribute is missing:

Code: Select all

<Signature offset="19">\x7F\x00\x00\x00\x00\x00\x00\x00\x00\x00\x04\x00\x00\x00\x44\x00\x00\x00\x00</Signature>
