Thank you very much. I checked in the order as you put it and the file explorer hide extensions for know file types is NOT checked.
When I go to the settings preferences default directory the Use new style dialog is not checked or the open all files below it either.
Now I did a test of a pdf file and it was a pdf file and changed the name to test.pdf. I then went to save the file with the same name at the beginning and hope the txt which I can see below in the save as bar would take out the .pdf and insert the .txt like it had done for many years but it said do you want to replace it and I said yes at least once and the file was an adobe extension in the file explorer directory and when I went to the file to open it, the adobe said it could not open the file. The file became a 1kb file in size and was still saved as test.pdf and I did not see it as a text file like I have to create for my work. I at least wanted to test with a file to see what would happen but I still have to take the file name and at least reduce it to test and note pad ++ does make the file .txt if there is not a period and some three letters that are there at all. Thank you for helping to have me investigate a few things today. Take care.
