Frequently Asked Questions
Why does my saved PDF file look like a blank white file icon?
This happens when the .pdf extension is missing, causing your operating system to lose the file association. You can usually fix this quickly by right-clicking the file, selecting 'Rename', and manually typing '.pdf' at the end of the filename.
Does the length of the filename affect how PDFs are saved?
Yes. If the combination of your filename and the folder path is excessively long, the application or the operating system may truncate the filename, which inadvertently drops the .pdf extension at the very end. Saving to a shorter path, like the Desktop, can prevent this.
Will repairing the application installation delete my saved PDF files?
No, using the 'Repair Installation' tool only scans and replaces corrupted program files and registry keys associated with the software. Your personal PDF documents and data will remain safe and completely untouched.
