How to create your own custom file list

Write the file path to get line by line in text file. Wildcard(*) is supported for the path that can not be fixed.

e.g. : udf.txt

/Users/*/Downloads/snork*
/Users/*/Documents/
/Library/LaunchAgents/*.plist

Tips

To save the target file to Disk Image (dmg format), check "Save file into dmg" in "Options". In my testing, this option allows you to finish the copy faster instead of requiring more disk space. If the copy destination file system does not support the extended attributes of macOS, sometime copying by diito may fail. However, it may be obtained by using the dmg option.

Note

These setting are recommended to triage more effectively.
