There is a faster, nonroot way to uncompress that file to another file.
Try "gzip -c filename.gz > ~/myfile.txt"  What this does is uncompress 
the file and pipes it to the terminal (standard output, actually), then 
the ">" symbol tells it to write whatever should be written to the 
terminal to the following file "~/myfile.txt", where the "~" symbol is 
shorthand for "my home directory".

As a footnote:
	">>" will append instead of write to a file.  "~user" (where 
user is a valid name) is a shortcut to the user's home directory.
