\(\text{FileExists}\)¶
You can use the \(\text{FileExists}\) function to determine if a file exists.
You can use the \fileexists
backslash command to insert this function.
The following variants of this function are available:
\(\text{boolean } \text{FileExists} \left ( \text{<filename>} \right )\)
The \(\text{<filename>}\) parameter is a text string encoded as a tuple
holding the name of the function to test against. The function returns
true
if the file exists or false
if the file does not exist.
Figure 135 shows an example use of the \(\text{FileExists}\) function.
