Want to reset "compression" attribute on folder and all subfolders, but not changing existing file compression settings.

-

i trying find way turn off ntfs "compression" attribute on folder , of it's subfolders, without changing setting on files might exist in folders.

we have emc vnx nas files , folders transferred on windows file server.  the windows server had file , folder compression enabled on data.  when files , folders transferred over, kept "compression" attribute on items. 

the vnx has own processing compression , deduplication, , having compression active on new files causing performance issues.  what need turn off compression attribute on folders, new files not compressed, don't want go , uncompress existing files.

the problem tools in windows (both command line "compact" , gui) either apply current folder, or subfolders , files.  there's no way i've found have apply current folder , subfolders without uncompressing files in subfolders, too.

i can list of directory names (dir /ad /s/b), , manipulate , feed script, we're talking lot of folders , hoping simpler method.

hi mike,

as said, not supported apply "compression" attribute on exist files not new files in same folder. may have workaround creating new files in new folders or decompress exist files.

for further information:
