This small command line tool collects all substrings of the filenames (without extension) of all files in a directory and all subdirectories. A substring is a sequence of alphanumeric characters that have no other alphanumeric characters to the side of the substring.

For example the filename image_2013_12_03.jpg has the substrings image, 2013, 12 and 03.

The tool can either list all found subtrings with their number of occurrences or list the files that have a given substrings in their file name.

FileSubstrings.exe [OPTIONS]

The options are:

-s : If this option is specified then, instead of the substrings with their occurrence count, the file names of the files that have the given substring are printed out.
-sl : Specifies the minimum length of a substring to be considered. The default value is 3.
-oc : Specifies a minimum number of occurrences of a substring to be considered. The default value is 2.
-c : Specifies the maximum number of results shown. The default is MAX_INT.
-h, --help : Prints the help.
-f : If this flag is specified then instead of the file names the full path of the files are printed out. This has only an effect if a substring is specified using -s.
