Тип файла E-Transcript File

Категория Файлы разметки документа

Описание формата файла

File created by E-Transcript Manager, a program used for creating certified electronic transcripts; contains transcript data recorded from a courtroom hearing; most commonly used by court reporting firms when creating legal transcripts for attorneys; created to reduce the file size of emailed transcripts.

E-Transcripts may also use the ".exe" extension, which allows the transcript to be viewed from a self-contained file. However, email filters often stop the delivery of ".exe" files. For this reason, the PTX file format was created as non-executable format to more easily bypass email server filters.

PTX E-Transcripts may be converted back and forth between ".exe" E-Transcripts.

NOTE: RealLegal, the developers of the PTX format, were acquired by LiveNote and then by Thomson West. Both the West and RealLegal brands are used to advertise and sell similar software applications. The Mac version of RealLegal E-Transcript Viewer is only available for Mac OS Classic, the predecessor to Mac OS X.
