Scan directories only about fatcat

[Gregwar]

Hello,

Why not
But maybe we should investigate why it crashed as well to prevent this from happening

Hello, thank you for answering.

Regarding the crash, I found the followings with my damaged image.
(I have to keep that image private, sorry...).

I use fatcat v1.0.6.
It seems that when a subdirectory contain file(s) with no filename (and/or pointing to cluster 0), recovering them results in crash. Like here in the listings:

f 0/0/1980 00:00:00                                 c=0 s=2 (2B)

or:

Listing cluster 914
Directory cluster: 914
d 6/1/2019 00:14:20  ./                             c=914
d 6/1/2019 00:14:20  ../                            c=912
f 0/0/1980 02:00:00                                 c=0 s=0 (0B)
f 0/0/1980 00:00:00                                 c=0 s=0 (0B)

The recovery gives:

Extracting /Android/data/com.dropbox.android/files/.@ to
/var/tmp/resc/Android/data/com.dropbox.android/files/.@
bash: segmentation fault (core dumped)  fatcat /tmp/sdh.img -O 1048576 -x /var/tmp/resc

in gdb:
Program received signal SIGSEGV, Segmentation fault. _IO_new_fclose (fp=0x0) at iofclose.c:48 48 iofclose.c: No such file or directory. (gdb)

I hope that this helps you to fix. Anyway, this program is lifesaving! Thanks for it.
