[File_Write] writes data to the specified file. Accepts two paramaters, the name of the file to be written and the data which should be written into the file. Optional -FileOverWrite keyword specifies that the destination file should be overwritten if it exists, otherwise the data specified is appended to the end of the file.

The file tags are protected by four different permissions. The user must have permission for all of the following in order to use this tag:
- Permission to use the tag itself.
- Permission to perform the file operation.
- Permission to work in the directory which contains the files.
- The filename extensions of the files which are being worked with must be allowed in Lasso Administration.
