I'm still very new to that subject as I've just switched to FM 14 Server this year and have migrated the file storage from container fields within to external (incl. relative paths).
I was under the impression that data entered in the Open storage field (i.e. "Contacts/Attachment/") would be directly used with the relative path specified above (i.e. [hosted location]/"Name of your File or Database".
In the above example the externally hosted file would be stored in a subdirectory where FM hosts your database (i.e. FileMaker/Server/Data/Databases/RC_Data_FMS/MyDatabase/MyDatabase/Contacts/Attachment).
For files stored on a different fileserver/drive, you'd specify it on the FM Server website (not sure if that's the same under FM13) under Database Server/Folders/Container Data Path (you can specify two locations). Then I assume you can select the external file server location in the open storage field in FM Pro.
Good afternoon Sven,
I hope your day is going well. Thanks so much for your help. I believe your answer has put me on the right track. I'll post an update after I attempt to configure some of the options you mentioned. Have a great day!
