It might be easier to use quotes than backspaces for filenames with spaces, though either approach is valid:
mv filename\ with\ spaces.svg filename\ with\ spaces.jpg
mv 'filename with spaces.svg' 'filename with spaces.jpg'
Tried it with quotes and it worked perfectly. Now it's all working fine.
One thing to note was that after trying all these things, or maybe from the overall instability the problem cause, the folder /dev/null (I think) could not be found at start-up. The computer still loaded, but it did cause some concern.
I know this is off the post's topic, but I'd love some help/re-assurance that my PC isn't gonna have a worse problem.
Thanks for the help, John.
Had almost the exact same problem awhile back - don't feel bad. Seems at least 3 people have done this. If I remember correctly, I had inserted a jpg, then saved the new svg file with the embedded jpg as the same name as the jpg file by mistake (slip of the mouse). Caused major freeze ups.
I don't believe so. I'd think that would be a separate issue.
