possible to modify external container field data (for 2nd pass optimization of media)
simple database, customer records, and we sometimes want to attach scanned PDF's (or JPG)
PDF's go into external container field relative to the database on the server - sweet
however, I would like to run an OCR pass on PDF's and optimize file size when saving (similar steps for JPG)
using same exact file name, permissions etc and replacing file (not using encryption of course to allow this)
when we try to load data, it's like it can't find it, the field is greyed out... is there some sort of CRC check going for keeping file original file tamper proof etc?
many thanks for input/help
