I often note that whenever Microsoft has a decision to make, they unerringly choose the worst alternative. Most of these are so small that I forget about them but today, I ran into one that is so perfect, I want to remember it forever.
As with my Macintosh, one way to rename a file is to click once directly on the text of the name. It will turn into a text entry and select the name, awaiting the new file name.
Occasionally, I want to append something to the name, eg, BACKUP, HOLD, TMP, DISCARD, etc. So that I can use the real file name for something new without having to lose access to the old file.
On my Macintosh, I open the name for editing and touch the right arrow. This moves the cursor to the end of the selection and lets me keep typing.
On my Windows machine, it moves it past the end of the selection and then past the period so that I am changing the file extension. While it's not impossible that this is what I want (on my Mac, select-all, right-arrow, delete delete delete), it's relatively rare.
Which is to say, Windows forces me to do extra work to accomplish the most common function. Like always. It also increases the likelihood of error.
How much does Windows suck? Just sayin'.
