Notes about the SPM file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The SPM file type is primarily associated with 'Source Package Manager' by Red Hat, Inc.. RPM is the Red Hat package manager. It is a program designed to build and manage packages of software including the source and binaries. Sources are often provided in source RPMs (*.src.rpm or *.spm or *.rpms). These sources include the pristine developer source code, any patches applied by the package builder, and a SPEC file that is used to tell rpm how to compile the package.
