 ## Bugs & Features
 
-The S3cmd client uses by default the so-called "multipart upload", which means that it splits the uploaded file into "chunks" with a default size of 15 MB. However, this upload method has major implications for the data capacity of the filesystem/fileset when overwriting existing files. When overwriting an existing file in "multipart" mode, the capacity is duplicated (the file is not overwritten, but rewritten and the original file remains - but the capacity is allocated by both files). This is a described swift bug for which there is no fix yet. But there is a workaround and that is to disable "multipart upload" on the S3CMD client side.

-this method is not recomended for large files, because it is not so fast and reliable as multipart upload, but it is only way how to overwrite files without duplicating capacity.
