How do I identify a file before changing it?
Check its location, name and extension first. Showing file extensions helps distinguish a document from an executable or shortcut. Renaming an extension does not convert the file, and a familiar name alone does not establish what a file contains.
What should I check before moving or deleting files?
Confirm that you have the right folder and a usable copy of anything important. A network share or synchronized folder may affect other people. If you see an access error, use a permissions guide instead of repeatedly retrying or changing ownership without understanding who uses the folder.
