Last I knew there was a limit to the number of files in ROOT (C:\)
Id set up a folder Text, then copy into that
Now.. I do not know if your text files are scattered over multiple folders
But for each folder in Dos.
From within the TEXT folder
Copy C:\ the full path to the folder *.txt
Then once you have verified the files copied
Go to the folder and del *.txt
I do not know if you can do it with a recursive command (All folders at once)
In windows
Open two file manager windows
Point one to c:\text
In the other do a search on .txt
Then copy (not sure this will work I really do not like Windoze)
Home was where I park it. but alas the.
