Snap2HTML is a small, free, portable tool which makes it easy to create a record of the files and folders on your PC. And that can be extremely useful for troubleshooting purposes.
Let's suppose a friend is having computer problems, for instance. You'd like to check his Program Files folder to see exactly what's installed, but as he lives far away there's no easy way to do that.
Email your friend a copy of Snap2HTML, though, and all he has to do is choose the root folder for the report, and click "Create Folder Snapshot". The program will then scan all the folders and files beneath this root folder, saving their details in a ready-to-email, self-contained HTML report.
And the best part is that the HTML report has the look and feel of Explorer. So you can browse the folder tree in the left-hand pane, choose a folder of interest, and immediately see each file it contains, their size and last modified date.
This is great for understanding more about a remote system, then, but Snap2HTML has other uses, too. In just a click or two you can have the program take a snapshot of your hard drive, for instance, which you could easily reference a week or two later if you'd like to know what's changed.
