mci_ipm_to_csv --debug file.IPM --in-encoding CP500 mci_ipm_to_csv (cardutil 0.6.4) parameters: -in_filename:file.IPM -in_encoding:CP500 -debug:True DEBUG:cardutil.cli:config_dir=None DEBUG:cardutil.mciipm:record_length=805306492 *** ERROR - processing has stopped *** Error detected in record 1 Invalid record length - value read was 805306492

If the first record has an invalid record length then the file is not valid.
The first 4 bytes should contain the length of the record in binary.

Closing as the file is not in IPM format

[adelosa]

It appears that this file is using the Mastercard Clearing Optimiser AutoEdit input file structure.
When I reviewed the file, it does have valid IPM records embedded within the structure with some additional file and record headers. I am not sure how these files are used and when you would use these in preference to a standard IPM file.
The bottom line is that cardutils does not support this format. I will leave this here as a "TODO" to see if there is
any interest in supporting this format.
