The purpose of this study is to explore Personal Digital Archiving, and its practices, reasons, and challenges in desktop and in ubiquitous environment such as desktop computers, laptops, mobile phones or smartphones, tablets, and cloud services. Moreover, it is also aimed to develop a model of Personal Digital Archiving process for desktop and ubiquitous devices. This study used Preferred Reporting Items for the Systematic Review and Meta-Analysis guidelines for searching and devising, and inclusion and exclusion criteria. The Search was conducted from selected repositories, databases, and core journals, potentially containing studies related with Personal Digital Archiving. Consequently, 21 studies were included through identification, screening, eligibility, and inclusion of studies process. It was found that people used multiple devices such as mobile phones or smartphones along with other devices. It was established that people had also used cloud services with different devices including computers and smartphones or tablets for Personal Digital Archiving. Five major categories of individuals’ Personal Digital Archiving practices, that is, backup, replication or duplication, reorganizing and updating, cleaning or removing, and migration of information were found. Moreover, emotional motives, technological causes, alternative access, easy retrieval, and task completion were the reasons to adopt Personal Digital Archiving. On the basis of findings of selected studies, researchers developed a four steps model of Personal Digital Archiving process, consisting of initiation, identification, action, and evaluation constructs. Personal Digital Archiving challenges were also identified such as the individuals had to face through the use of desktop and ubiquitous devices including technical, fragmented and overloaded information, lack of training and expertise, and psychological and miscellaneous challenges. Personal Digital Archiving process model is based on the extracted data from studies published worldwide, and it is useful for both desktop and ubiquitous devices with reference to Personal Information Management context. The findings of the study will be helpful for software designers and android application developers to design and develop users’ centered Personal Information Management software.
