How do I validate a .pcv file?
To validate a .pcv file, read the first bytes of the file and compare them against the known magic bytes (55 55 AA AA) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .pcv files?
There is no officially registered MIME type for .pcv files. Systems typically use application/octet-stream as a generic fallback when handling this format.
