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"
"Maple 2020" > "Preferences" > "Security"
