Comparison rules

During folders comparison, Synchronize It! consider some files as same. You can affect which files should be handled as same by choosing one of comparison rules:

Date + size Default rule, suitable for most cases: files are same, if they have same date and size.
Date or content Modification of default rule, suitable if you think you have same files with different dates. Files with same date and size are still considered as same, but in addition files with same size and different dates are compared byte-by-byte to check if they are same.
Content Strict rule, which does binary comparison for all file pairs. Using this rule will make synchronization slower. This rule is ideally suited for CD verification after burning
Size only Files are considered to be same if they have same size. It is only good for some log files and similar.

Tip #1: Synchronize It! always matches files with same names only.

Tip #2: Date comparison in all rules takes into account global time-related options, such as Ignore 2 secs difference etc.


Synchronize It! supports different synchronization modes, called Actions, which you can choose depending on your task. Actions are different in a way they handle each file types. Synchronize It! separates several file types during synchronization:

  • same files - they are not copied, but could be included in list;
  • files found only on source folder (left side of file list);
  • files found only on target folder (right side of file list);
  • files present on both sides, but source file is newer;
  • files present on both sides, but target file is newer.
Following table describes how each action handles these files:
Action source only target only source newer target newer
Synchronize copy >> copy << copy >> copy <<
Update target copy >> --- copy >> ---
Backup copy >> delete copy >> ---
Duplicate copy >> delete copy >> copy >>
