I hear this horrifying question/statement frequently: "I deleted several files from my project using Windows Explorer the other day. I was pretty sure that none of the files I deleted were important. Anyway, now when I open my RoboHelp project, I get error message galore! What did I do wrong?"
One of the worst things you can do to your RoboHelp project is remove files from the project folder using Windows Explorer. Why? If the RoboHelp project is using the files you removed you can, at the worst, corrupt the project. At the best, you’ll receive error messages as RoboHelp attempts to communicate with the deleted files.
Instead of deleting project files via Windows Explorer, you should delete the files via RoboHelp’s pods. But there is a problem with this approach: if the project file is not being used by RoboHelp (for instance, a CSS file that you no longer need), the unused file will not appear on any of the Pods. What’s a RoboHelp developer to do? Read on…
In all versions of RoboHelp (including RoboHelp 7, 6, X5, X4 and X3), open your project and then choose Tools > Reports > Unused Files.
The Reports dialog box appears with the Unused Files tab selected.

Use the Print button located in the lower left of the dialog box to print the report. Then, with the printed report at your site, feel free to delete any of the files on the report via Windows Explorer.
