On MacOS:
In some cases there is a leading / in the paths of the crc stamps file, while in some others there isn't.
E.g.
from a desktop folder,
“/my folder name/sub folder/file name” .....
But on a CrcStamps file from an sd card, these lines written as:
“my folder name/sub folder/file name”
To make sure this is harmonised. The paths in the CRCstamps file should be relative, so no leading slash (Mac) or backslash (Windows).
