|
# For selection: it will generate one file containing the checksums with file names
|
|
|
|
# [and with paths if they are in another directory]
|
|
|
|
# the output checksum filename will be checksum_timestamp.checksum_type
|
|
|
|
# For file: if the file is a checksum, the plugin does the verification
|
|
|
|
# if the file is not a checksum, checksum will be generated for it
|
|
|
|
# the output checksum filename will be filename.checksum_type
|
|
|
|
# For directory: recursively calculates checksum for all the files in the directory
|
|
|
|
# the output checksum filename will be directory.checksum_type
