Hello, after discussion with Marc A Kaplan from IBM I finished with this solution. So I am sharing it with all other user just in case you need it in future.
Example placement policy file: /* --- Enable .avi so it will not be denied by default --- */ RULE 'enable_avi' SET POOL 'data' FOR FILESET (nfsexport) WHERE RegEx(lower(name),['\.avi$']) /* --- Deny all following extensions --- */ RULE 'deny_files' SET POOL 'system' FOR FILESET (nfsexport) WHERE RegEx(lower(name),['\.avi$|\.mp[ae1234]$|\.mpe?g[23]?$|\.eml$|\.idx$|\.mbo?x$|\.msg$|\.ost$|\.otf$|\.pab$|\.pst$|\.aac$|\.aif*$|\.as[fx]$|\.au$|\.flac$|\.m3u$|\.midi?$|\.mov$|\.ogg$|\.qtw?$|\.ram$|\.rmi?$|\.rmvb$|\.snd$|\.swf$|\.vob$|\.wa[vx]$|\.wm[av]$|\.wvx$|\.bmp$|\.dib$|\.eps$|\.gif$|\.img$|\.jfif$|\.jpe?g?$|\.pcx$|\.png$|\.psd?$|\.raw$|\.if$|\.spiff$|\.tif*$']) /* --- Enable every other file extensions --- */ RULE 'DEFAULT' SET POOL 'data' Bye, Pavel -- Ing.
