About this app
KURS on-line Reader allows you to open and view PDF documents. When launched, the app scans your device for documents that might be opened. Documents are automatically added to the app library. SFPDF and PCDOC files are used to protect documents from unauthorized access, copying and distribution. This is a special tool that preserves the confidentiality of digital publications. Warning! Downloading the KURS on-line Reader does not guarantee the opening of a protected file. To successfully open a file, you may need a serial number, which is provided by administrators of the KURS digital library system.
