Hey Nirmal,

If you know that no other documents will have the name "TEMP", you can use a search repository activity to search for all documents within that folder path who's name starts with "TEMP", which would look something like '{LF:Name="TEMP*", Type="DB"} & {LF:LOOKIN="[FolderPath]"}'. 

Then you would use a For Each Entry activity to grab all the entries you found, then use the Delete Entry activity to delete each of those. 

If you can't guarantee that documents will not have 'TEMP', you could also add a metadata field which would also signal to workflow that the document should be deleted and also search for that field value.

If you don't know how many temporary forms you will be creating, this could be the best approach. However, if you do know how many and the specific location of each saved form, then you could just use the Find Entry activity to specifically find each form, which will save some time because you won't need to search through the repository.

Hope that helps,

Kevin
