The term "Lolcams" was frequently associated with early internet humor sites (similar to early 4chan or Ebaum’s World) that hosted short, funny webcam clips. These were often low-resolution (240p or 360p) and shared in AVI or WMV formats.
Open the file inside a Virtual Machine (like VirtualBox) so that if it contains a virus, it cannot escape to your main operating system.
VLC contains its own internal codecs and does not rely on system-wide "codec packs," making it much safer for opening unknown files.
If you are determined to view the content (for example, for digital archeology or lost media research), use a "sandboxed" approach:
A standard .avi video should be several megabytes at minimum. If the file is only a few kilobytes (KB), it is likely a shortcut or a script designed to execute code, not a video.
Files with names like "GM 0649" are often generated by older digital cameras or automated recording systems.
Based on available information, is not a widely recognized software, historical event, or standard media file . Given the naming convention—specifically "Lolcams" and the ".avi" extension—it most likely falls into one of three categories: a specific piece of lost media , a legacy viral video , or a malicious file associated with older peer-to-peer (P2P) file-sharing networks.
Providing that context can help narrow down exactly what was inside.
