How do i Extract a jpg from an unallocated directory

Which filesystem?

If it is a school exercise, most probably the single JPEG images are contiguous, so you need to find the start and end of each and then dd it to a new file

Autopsy/Sleuthkit have carving capabilities

But of course there are tens of softwares capable of doing this kind of automated carving for a given filetype (in this case it is more "data recovery" than "digital forensics").

Another free tool that works pretty well is called "photorec" (photo recovery). It also works well on non-image file types. https://www.cgsecurity.org/wiki/PhotoRec

Thanks for the help i will defenitly try it. i tried "icat" ,after i found the inode, into a jpg file but it turned out it wasn't a jpg but something else.

Search for the header and footer of an jpg file. Extract anything between.

Oeps - I didn't check the URL.
I use Garry Kessler website to extract all kinds of files in the dd image. The search can also be done in a hexviewer.
Searching for the footer or trailer is even not necessary; just select a large part and add the appropriate footer at the end of the file.

Yep, that is a very good source for this info ) .

Usually hex viewers/editors are usually slowish when searching, a tool that is suitable and works just fine/fast is gsar (in Windows)

though unfortunately it has some limitations with the offsets, so it is a problem going through largish disk images becuase addresses "wrap" around.
