Search Method 'File Name'
Compare method
Compare all characters of a file name
Compare only characters at the beginning of a file name
This option enables you to compare only a certain number of characters at the beginning of a file name and ignore the rest of the name.Compare only characters at the end of a file name
This option enables you to compare only a certain number of characters at the end of a file name and ignore the rest of the name.Ignore characters at the end of a file name
This option enables you to ignore a certain number of characters at the end of a file name.
Ignore specific characters from the file name
Here you can specify multiple characters that will be ignored when comparing two file names.Example: Specifying the minus character (-) will treat the file names "data-01" and "data01" as a duplicate file name.
Ignore text patterns from the file name
Here you can specify multiple text patterns to be ignored when comparing two file names. Multiple text patterns must be separated with the slash char (/).Example: The text patterns "001/002" will treat the file names "data001" and "data002" as a duplicate file name.
Find similar file names
Algorithm
The following algorithms are available to search for similar file names:SmartMatch
FuzzyMatch
Levenshtein
Ratcliff-Obershelp
MatchDiff
WordMatch
FuzzyPercent
Simil
All algorithms except WordMatch performing different text comparisons and calculations between the two file names to calculate the perceptual match between them. The algorithm WordMatch splits the file names into words and calculates the perceptual match by comparing the words. All algorithms are not case-sensitive, meaning no distinction is made between uppercasing and lowercasing when performing comparisons.
Match
This is the degree of match that must exist between the file names in order to be offered as duplicates.Delimiter
Here you can specify the delimiter characters for the algorithm WordMatch to split the file names into words. For example the file name "aa_bb_cc" will be split into the word collection "aa", "bb" and "cc" by using the delimiter character space (" "). The standard delimiter characters are: space, comma, underscore, dot, semicolon and minus. You can add or remove any number of delimiter characters.Examples
The following file name comparison examples give you an overview which algorithm could be suitable for your search for similar file names.The duration at the right table column shows the necessary time to perform 10.000 file name comparisons.
