<br>
After the taging, when the digikam write the metadata back (face tags) <br>
its overwrite the file big parts with 0x00 bytes, so its kill the file<br>
<br>
(its happen twice, with tiff files)<br>
<br>
how can i prevent this, or there is a switch to _always_ make a backup? <br>
(even multiple backup is there is a backup?)<br>
<br>
Thanx<br>
