I previously had a problem of managing and updating my media links in RootsMagic but found a "Fix" that solved the problem as well as made my source Media more readily available and easier to find.
I am attempting to reduce my paper files, and as I move toward a goal of 99+% digital copies of source media, it necessitates managing and occasionally adjusting my file naming conventions. An advantage of moving toward full digital copies is I can place copies of files associated with something like the marriage record for say John ALDEN and Priscilla MULLINS in both my ALDEN and MULLINS folders which makes it easier to find appropriate source information when doing additional research on either family.
I have a folder with sub-folders on my hard drive with all my Genealogical information.
As time goes on I may find I need to re-name or re-organize some of the specific files. This created the issue of needing to re-establish correct links for media in RM7.
To solve the issue of links to RM7 I also have also placed a folder in the root directory of my C: drive called "RM7 Media."
Having all the files used as media for RM7 in a single location, makes it easy to duplicate this folder and all its contents on both my desktop and laptop computers. When I create a shareable CD for my cousins each Christmas, I can send along a copy of this single folder with instructions on where to copy the "RM Media" folder so they have fully functioning links to all the sources used for my research.
A side benefit to this is that I don't have to worry about preservation of my important Genealogical Research as I am following Dick Eastman's L.O.C.K.S concept ( Lots of Copies Kept Separately) as I have copies in Ohio, TX, CA and OR that are updated annually along with my normal back-up copies of external media and in the Cloud.
Enjoy and good hunting.
