## Steps to reproduce
For systematic reasons, I tried to rename a Test Case folder within Katalon Studio in such a way that its name then contained a dot (‘.’). Katalon Studio neither warned me nor prevented me from doing it.
After that I got a hint to fix errors in the script before switching to the Manual View. But I couldn’t find any such errors in the open Test Case scripts. Since I had already guessed that Katalon Studio could not handle my renaming so well, I undone my change.
So far everything seemed to be fine. Until I reopened my project and found that all my Test Cases inside the previously renamed folder were completely empty except for the import lines block!
## Expected Behavior
Katalon Studio should prevent me from renaming a Test Case folder to a name that contains a dot if it can’t handle it! Under no circumstances should Katalon Studio empty or delete any Test Case scripts!
## Actual Behavior
Katalon Studio has emptied my Test Case scripts except for the import lines block!
