Custom Backup Tool v1.4

Changelog:

1. Added the following features as options that can be changed from the dirs.txt file:

• Blacklisted directories (ones that will be skipped by the program);
• Hidden files (ones that may or may not be skipped);
• Hidden operating system files (for Windows, that may or may not be skipped).

2. When an exception is encountered, the program immediately opens the created errors.log file.
