data- file corrupted

Hi, this became super annoying, for I'm struggeling with this for years now, and I cannot solve it.
I have saved a scene file. Nothing special, but the problem is, as I delete it, the basicGenesis 8 Female file loaded with an error message, that this (deleted) file is missing.
Somewhere must be a reference hidden my morph assets, but I just can't find it.
Are there any advanced tools or methodes to track down that scene file reference?

Check the log file, it should contain which file is requesting the missing file.
Did you use anything from File>Save As>Support Assets or just a regular scene save?
I know which file is missing. I just don't know, where in all the *.dsf data files, it demands for that scene file.
Yes, I always use at a regular basis, for creating my morph targets. I know, that sometimes it's possible to have a scene file as a reference, instead of a figure file.
This can all happen by mistake. I'd just like to know, how to track down those mistakes. The log file only tells me, that a file is missing. It doesn't tell me where exactly, the requirement for this file is located.
Uncompress the file, using the Batch Convert pane or soemthing like 7Zip, open in a text editor, and search for the file name (remembering to replace spaces with %20 and so on in the name).
yup, did that with the basic Genesis 8 Female.dsf and several character dsf's.
EDIT:
I did that search on the basic Genesis 8 Female dsf and *.duf files. No results.
With every character morph installed, this would take a lot of time.
So is there no short cut for finding this corruoting file reference?
UPDATE:
with notepad ++ , I did a search on that file with all open files.
0 results out of 198 open *.dsf files.
Try deleting the DSON Cache (Edit>Preferences) though I wouldn't expect that to help.
