Viewing Catalogs and Saving Files

Saving a File

NOTE

Highlighting a filename in the To: directory box has no significance. The file

 

cannot be placed inside another file.

 

 

7.Press Copy Now to execute the operation. The message: “Copying file” is displayed during the copying process. Upon completion, the status bar reads:

“C:\START\RENAME.TRC file copied”. You have now copied the file RENAME from the C: drive to the A: drive.

Deleting a File

1.To access the Delete menu, press File, Delete.

2.Select the type of file you want to delete (setup, state, trace, limits, screens, or corrections). In this example, you are deleting a trace file; press Type, Trace.

3.Select the drive and directory where the file you wish to delete is located. In this example, choose C:\START\. Use the navigation keys (Dir Up, Dir Select, step keys, front panel knob) to highlight this location in the Path: field. (Refer to “Locating and viewing files in the catalog” on page 45 for more instructions.)

4.Select the file you want to delete. In this example, choose the file RENAME.TRC. Move the cursor with the navigation keys to highlight the file name.

5.Press Delete Now. The message: Deleting file pops up on the display during the

operation. Upon completion, the status bar reads: C:\START\RENAME.TRC file deleted. Your file is now deleted and is no longer visible in the directory displayed on your analyzer.
