dump file visualization for example( in.srd.mixture/pure)

How to visualize dump file for in.srd.mixture.
I tried to visualize this by VMD but it had errors

ERROR) Unable to determine file type for file ‘dump.srd.mixture’. Assuming pdb.
PDB file ‘dump.srd.mixture’ contains no atoms.
ERROR) Could not read file dump.srd.mixture
ERROR) Loading of startup molecule files aborted.

Can i visualize just file from XYZ type?
How to recognize type of dump file?
Thank you for your help in advance

This is a VMD question and should be posted to the VMD mailing list. But before doing that you should simply read the VMD users guide and learn how to set the file type when VMD cannot recognize it from the file name.
