Textfile
A textfile is a sequence of bytes, each of which represents a character. Usually the ascii character set is used for encoding.

Textfiles are very common on Unix systems as they encode all sorts of information in flexible, programmer-visible ways. Most programming languages encode programs as textfiles, too.

Tallying
Collecting information about files, directories and volumes. Tactile Interrogator can show a lot of information, this data is aquired through a process called Tallying.

Most of tallying involves reading the filenames in directories (using the readdir(2) system call) and then getting information about each file (using the stat(2) system call). This is the same process that the ls program must go through every time it is used on a directory. In addition, other information such as volume information is gotten through other system calls. Tallying is multithreaded; at any given time, multiple directories are probably being tallied through as you use Interrogator.

The tallying process is similar to using the du unix command. It simply takes a long time to read all of those directories and the information for all of the files. The biggest difference between du and tint is that du reads all of the information about all of the files and directories, adds up megabytes per directory, prints out totals, and throws away all the other information. Interrogator reads all of the information about all of the files and directories, saves it in a cache, keeps it updated in case it notices any changes, and calculates directory totals for your viewing, instantly based on the cached data.
