Hi @smithmrk ,
It seems that the Find files in folder by path action also searches within subfolders - i.e. folders underneath /1099/TEMP.
You may be able to get away with using Pattern for the File Search Mode, then filter the results, filtering for the exact file path and filename? Using OneDriveSearch for the File Search Mode doesn't return the full path of the file so we can't filter the files based on the path.

In the sample results below, note the two paths as returned by the Pattern search mode:
{
"Id": "b!nzu48wrMZk6wUa2mtk43v-BAQOSBY366FHKIOJSAKCX54C4",
"Name": "Test1.docx",
"NameNoExt": "Test1",
"DisplayName": "Test1.docx",
"Path": "/1099/TEMP/Test1.docx",
{
"Id": "b!nzu48wrMZk6wUa2mtk43v-F8iPoxJAxKiXUPzIa7meKD4I4K",
"Name": "Test1.docx",
"NameNoExt": "Test1",
"DisplayName": "Test1.docx",
"Path": "/drives/b!nzu48wrMZk6wUa2mtk43v-F8iPoxJAxKiXUPzIa7meKhmZ2_IOOwTJX7DMvB0_J0/root:/1099/TEMP/sub1/Test1.docx",

Hope this helps.
Ellis
