Support of H86 files

[csomosa]

Hi All,

one of our customers is using .h86 files which file type can be detected correctly with ExifTool 10.14, but the newer versions recognize these files as txt:

Code Select Expand

[{
  "SourceFile": "original_0532d47b658a2d1b6b4b3fd41d3556bf.h86",
  "ExifTool": {
    "ExifToolVersion": 12.28
  },
  "File": {
    "FileName": "original_0532d47b658a2d1b6b4b3fd41d3556bf.h86",
    "Directory": ".",
    "FileSize": "1643 KiB",
    "FileModifyDate": "2022:05:06 11:16:39+02:00",
    "FileAccessDate": "2022:05:06 11:16:26+02:00",
    "FileInodeChangeDate": "2022:05:06 11:16:39+02:00",
    "FilePermissions": "-rw-r-----",
    "FileType": "TXT",
    "FileTypeExtension": "txt",
    "MIMEType": "text/plain",
...
  }
}]

Would it be possible to support H86 files again?

Best regards,
Anna

ExifTool never "correctly" identified H86 files:

Newer versions recognize these as text files, which is actually correct.
