Sharing data among computing systems can include receiving, using a processor, a data transfer event indicating a transfer of a data file from a source system to a target system, querying, using the processor, the source system for an operating system executed by the source system and a file type of the data file, and querying, using the processor, the target system for an operating system executed by the target system. A target application can be determined using the processor. The target application is adapted for execution on the operating system executed by the target system and is adapted for operating on the file type. Installation of the target application on the target system can be initiated. Further, transfer of the data file from the source system to the target system can be initiated using the processor.
