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.
There's even an option to link the files in your HTML report to those on the drive (assuming they're on the same PC, anyway). Browse the folder tree, and if you see a file of interest, you can just click the link to open it.
