The size of the file, as decompressed outside the archive.
The size of the file, as decompressed outside the archive. If an archive is open for read (i.e. has been scanned or decompressed), this information will be read from the archive headers. If an archive is not open for read, the control will retrieve the information for the corresponding value of FileDecompressedName from the local file system.
A value of -1 will be returned in case of an I/O error.
The size of the array is controlled by the FileCount property.
This property is read-only and not available at design time.
