How do I fix the 'permission denied: no write access' or 'no read access' Error When Reading/Writing Files or Creating Temporary Files in Maple?

If you are either trying to read/save a file or create a temporary file in a directory/folder for which you have read/write access, but receive an

Error, (in FileTools:-TemporaryFilename) permission denied: no write access (Maple)

error, or something similar, your security settings may need to be updated.

FileTools:-IsWritable( "C:/" ); # false
FileTools:-TemporaryFilename(); # error
FileTools:-TemporaryFile(); # error

To either disable the security setting (uncheck "Enable engine security"), or add exceptions, you can navigate to:

Windows or Linux:

"Tools" > "Options" > "Security"

Mac:

"Maple 2019" > "Preferences" > "Security"
