In the Export dialog, the export file type "as original" is badly phrased. When you pick this option, you are exporting the original file in the original file format with no edits. To export your edits, you need to pick JPG or TIF as the file format.
If I am reading your description of events correctly, you really need to rethink your work flow.
You appear to be overwriting the original files with the exported files. This is a very bad thing.
You should have your original files and the exported files in separate folders.
Since the exported files can be exported again at any time, you do not need to store them after you use them for whatever purpose you are exporting them for.
Your catalog should be located outside the folders used by your cloud sync service since this will cause lots of files to be uploaded that you don't want uploaded.
So as original would say littarly as orginal. Ok. Than I know that.
2 reasons why i want to do do it like that. Space, and that i realy don´t need the original, since they are not looking like i want. But i will think one more time over it. thnx.
The problem with destroying the original file is that you cannot ever go back into LR and change any of the edits.
On the other hand if you delete the separate exported files after you use them or upload them to a website or whatever you wanted to do with them, you get back the space used by the new file and can recreate the exported file any time you need it again.
