Data Modes; Figure 4.2 File Naming Convention - ashtech Z-Xtreme Operations & Reference Manual

The U-file is automatically named according to a naming convention that includes
the site name, session, and day of the year. Figure 4.2 outlines the file naming
convention.
• The first letter is the file type.
• The next four characters indicate the site information. If you have not
entered a site, then these four characters are replaced by underscores
("____"). If you have not entered a site during the course of the session,
the last site information entered in the previous session is used. If the site
has been entered several times during the course of the session, the last
entered site information is used.
• The next character is the session identifier. This field automatically
increments from A with each new session, ending with Z. After 26
sessions are created, the session identifier resets to A, and the first
character of the year changes to A. Then, once again the session
identifier increments one letter with each new session.
• The next two characters indicate the last two digits of the year when the
session was terminated (e.g., 00).
• The file extension indicates the day of the year when the session was
terminated (e.g. Jan. 1 is day 001; Dec. 31 is day 365).
