I can verify that the ../tmp folder will always be available. Right now things are very static. I have manually created all the directories and given proper permissions(777) just for testing and ease of development.
When using move(..), I wind up getting the error move to /mnt/fds-phx/plsTrans/9DFA109A-B562-1BEA-064686FE31CA2F93/tmp/ failed: Is a directory at Lib/PLSParse.pm line 130.
The output I get from the paths I have created is below.
$transFile = /mnt/fds-phx/docTmp/coded/1.tif
$transPath = /mnt/fds-phx/plsTrans/9DFA109A-B562-1BEA-064686FE31CA2F93
