VCOMP creates pax files to reduce the size of general-purpose data without losing information. The compression is lossless, so decompression restores the data to its original form.
A pax file is a compressed data file rather than a document intended for direct editing. VCOMP is used to decompress it and provide access to the recovered data.
Open the file with VCOMP, the software associated with this format. Use VCOMP to decompress the file and restore the original data.
VCOMP files are normally converted by decompressing them with VCOMP. The result is the original uncompressed data, which can then be saved or converted with a program that supports its recovered format.
