This will get the resource fork data:
put url ("resfile:"&tLocalFilePath) into tResDataVar
This will restore it to a file:
put tResDataVar into url ("resfile:"& tLocalFilePath)
The compress and uncompress functions are great. In my tests here gzip
seems quite efficient: on text it often reduces the data size to about 30%
of the original.
