The following steps were taken to recover these ASC files due to
an error message generated upon opening them in LTspice involving
the first line of characters.

Open the ASC file in a binary text editor, such as: EditPad Pro 7
Convert / To Windows (CR LF)
Save
Close
Re-Open it in Windows Notepad
Copy all lines after the first line
Select some other program which had been previously drawn in LTspice, and...
Open it in Windows Notepad
Delete all lines after the first line by pasting and overwriting them
Save As (and overwrite) onto the ASC file
Repeat for each file...;-)
