Data file exported by a variety of different program; typically saved in a more standard format than the program's proprietary file type so the file can be opened and read by other programs; often exported by selecting "File?Export" within the program. Some programs that export EXP files include Intuit QuickBooks and IBM iSeries software.
Microsoft Visual C++ exports source codes, project information, references, and forms, which can be opened by other programming languages, like Borland C++, Visual Studio, and so on. This is very useful for sharing data with different users. Intuit QuickBooks is a financial application that uses the same file extension in transferring and sharing data to other systems. To save data into a file with an .exp extension, the user needs to access the "export" function under "File" found on the menu bar. The data can be transferred over to your project using the "import" command under the same location.
Another version of the EXP extension is described as "Aurora Expert Trace File," created by the application Trend Communication Aurora Expert. The file with an EXP format will contain trace info for data communication. This includes the recording of the various paths used to transfer data across different devices, such as PPP, IP, V5, ISDN, and Frame Relay Systems.
