Dear Gosia,
as far as I know the naming scheme of files in the $prefix.save
directory is that the .xml extension refers to (iotk-written) textual XML
files, while .dat refers to binary files (probably still written in iotk fmt)
Since magnetization is stored binary (I guess), the files dumped should have
extension .dat.
Usually, QE does not care whether .xml or .dat is used, and goes ahead
anyway... probably this is not implemented in the piece of code you are
referring to.
For the charge density, eg, PW/src/potinit.f90 reads
!
filename = TRIM( tmp_dir ) // TRIM( prefix ) // '.save/charge-density.dat'
exst = check_file_exst( TRIM(filename) )
!
IF ( .NOT. exst ) THEN
!
filename = TRIM( tmp_dir ) // TRIM( prefix ) //
'.save/charge-density.xml'
exst = check_file_exst( TRIM(filename) )
!
ENDIF
!
brute force solution:
convert .dat into .xml using iotk (eg from espresso/bin)
iotk convert file.xml file.dat
longer term solution:
fixing the sources should be very simple (worst case scenatio just change .xml
into .dat, better to support both of them)

Dear Quantum Espresso Users and Developers,
I faced the following problem trying to calculate the band structure for my
system:
I did my scf calculations including SO with non-zero starting magnetization.
Then I tried to calculate the band structure, and the program crashed due to
the lack of magnetization.x.xml file.
The problem is that the only file I can find is the magnetization.x.dat.
How can I obtain the xml files for magnetization? Is it posible from the dat
file?
I use QE 5.3.0 version.
Thanks in advance,
