Will renaming a file change its CRC?

As stated, will renaming a file change the CRC? I've 开发者_JAVA技巧checked in plain text files and it didn't. Does this apply to all files of all formats?

CRC is calculated on the contents of the file. The file name is just an entry in the file system that allows access to the file. It's not part of the file itself, so it's not part of the CRC.

CRC is normally calculated on file content, but there's no prison sentence prescribed for writing a CRC utility that includes the filename. Check your particular utility's documentation, or I'd say it's safe to trust the results implied by your experiment.
