Hash tags for files on one drive
I've got large folders with many files and they are uploaded to one drive (OD). Then over time I modify a bunch, now I want to update the files, but I don't want to do this one at a time. I want to say OD, upload this folder. BUT, I don't want to (a) pay for the cost of uploading everything, (b) I don't want duplicates created of the files that were not changed.
Soln : create a hash for each and every file that is in the folder and leave that as a proxy for the file on the local machine. Saves lots of storage space. Now when I want an update of the folder, only files that are new or files that don't match their hash tags will be uploaded.
