The compression level to use; this is valid only when using GZIP compression. A lower value results in faster processing but less compression; a value of 0 indicates no compression but simply archiving
Update Filename false * true
* false
If true, will remove the filename extension when decompressing data (only if the extension indicates the appropriate compression format) and add the appropriate extension when compressing data
