#TempFile

Description

The complete file specification (Drive:\Path\FileName.Ext) of a session-specific, non-overlapping temporary file.

Examples, Notes and Instructions

• #TempFile uses the equivalent "short names" for the file and path whenever possible.
• The temporary file name is constructed in five parts:
   

  ~~		literal prefix, always two "~" characters
  %~sn0		Expands to the short file name of the script that is running when .GetTempFile is executed.  If this value is unavailable, the literal characters "%~sn0" will be part of the temporary file name.  This usually occurs because .GetTempFile has been run from a  command prompt.  The file name is still valid with the "%~sn0"  characters in it and can be used normally.
  -		literal "-" character, separates the short filename from the "random" number
  nnnnnnnn		The "random" part of the file name, loosely based on the current Precise Log Time (see #LogTimeP).  While this is not a truly "random" number, it is random enough to allow multiple simultaneous runs of the same script, on the same machine, using the same temp folder, with an extremely low chance of conflicts.
  .txt		the literal ".txt" extension allows easy viewing and editing of the file with a double-click (as opposed to ".tmp")

• All of the Mount/\Commands for manipulating temporary files will use the current value of #TempFile  as their target. These commands are:
  
  ReadTempFile   WriteTempFile   AppendTempFile   CheckTempFile
  MarkTempFile   TouchTempFile   ShowTempFile     HideTempFile
  SortTempFile   ClearTempFile   DeleteTempFile
   
• Constants with names in Mixed Case contain commonly needed data whose exact value(s) vary based on conditions at the time of update.
