Diff

Legend:

Differences:
- No differences detected
- File is different, or directory contains differences
- File is only found on left side, when this happens to a directory, it is only counted as 1 difference
- File is only found on right side, when this happens to a directory, it is only counted as 1 difference
Type:
- This is a directory with sub items. After the directory name, it lists as info the number of differences over the total number of sub items
- This is a file. If both sides contain the file but are different, it lists as info the different strings
Info about the file/directory listed in between parenthesis.

Options:

Display all items
Display only same files (Displays all directories)
Display different items (Does not display synced directories)
- Do not display left only items
- Do not display right only items
