After years of accumulating scan results, my HDD is filled up to within 2GB
of its 1TB capacity, so operations of most kinds are excruciatingly slow. It
really does not like editing 2GB text files in LeafPad.
Nobody should ever do that: learn sed, awk, etc. Also, compressing text
files is very effective, as in dividing the size by ~10 with XZ. You can
start your command line with (z|bz|xz)cat. less can read those compressed
formats too.
sudo chmod -R 755 Thumb256A
With such permissions, only the owner (root, apparently) can write. You can
change the owner (and the group) with 'chown':
$ sudo chown -R $USER:$USER Thumb256A
Or you can use a graphical file manager, e.g., 'sudo caja' for Trisquel's
default file manager.
