Zusammenfassung: | The invention provides a compression method and device of a file system, a device, a storage medium and a program product, and relates to the computer data compression technology. The method comprises the steps of obtaining the to-be-written data, and reading the compression information corresponding to the to-be-written data; dividing the to-be-written data into a plurality of data blocks according to the compression information, and compressing each data block to obtain a compressed block; filling preset data in each compression block, wherein the compression block and the corresponding data block occupy the same logic space of the file system; and compressing each compression block, and writing the compressed data into a storage device. In the scheme, the preset data is supplemented in the compression block after the to-be-written data block is compressed, so that the compression block filled with the preset data and the corresponding to-be-written data block occupy the same logic space of the file system, |
