permissions -- plz help

[Maaz]

Dear Gurus

how can i implement the permissions on the folder(say c:\data) so that users

0, Read the file(s)
1, cant delete the file(s)
2, cant delete the contents(previously written data) of the file(s)
3, but they can append the in the file(s) i.e they cant change/remove previously saved data in the file, but they can append the data.

plz help me implemet the above mentioned permissions.

I believe only 0, 1, 2 points are possible using NT permissions..

3rd point can be achieved only thru applications using DB or something like that. I am not sure whether it is worth writing an application to do the work..

Dear Ganesh Babu Many Thanks for ur quick reply/help

from windows help

Create Folders allows or denies creating folders within the folder (applies to folders only).

Append Data allows or denies making changes to the end of the file but not changing, deleting, or overwriting existing data (applies to files only).

i try me level best to implement the permissions as i asked for. but upto now failed.

I gave the read permissions at the folder level for Everyone, and in special permission I gave Create Folder/Append Data permissions to EveryOne .. but of no use.. even user dosnt append the data, although i have given the special permissions of Create Folder/Append Data

Any One can help Plz

Ok... the basic problem with giving users the ability to only "Append" data, is that by default, most file open commands are for read/write. You have to specificly open a file in "Append" mode, rather than read/write mode. Unless you create an application than will directly open a file in append mode, the permissions will never apply.

The other solution (offered by Ganesh) is the easiest to achieve... Write a web application that appends records to a DB, and has no method for editing or deletion.

Try CREATOR/OWNER instead of special permissions!

Also, do not use Everyone, Create new groups and add users to each group respectively, next give permissions accordingly and last remove Everyone Group.
