How to Restrict File Size in a Specific Folder Using FSRM or Other Methods?

Question

Hello everyone,

I need to restrict the size of every single file that is stored in a specific folder on our File Server. The main objective is to avoid large files being stored and transferred on the network. I've tried using File Screening Management in File Server Resource Manager (FSRM), but it only allows me to put restrictions based on file type and it allows to give a limit to Folder using Quota Template, but this cannot be applied to files.

The actual requirement is to enforce a size restriction on every file in the folder, regardless of the file type. For example, if I set the maximum file size to 5MB, it should check every file being saved, moved, or downloaded into the folder. If a file exceeds 5MB, it should trigger a warning message ideally, if that's not possible , then give a hard limit on the file operation and should not allow operation to succeed.

We use Windows Server 2012R2

Is there any other method to achieve this using FSRM, or another method or tool that can accomplish this? Any guidance or detailed steps would be greatly appreciated!

Thank you!

Hi,

I don't think you can limit file size using FSRM. FSRM can only limit the size of a given directory using directory quotas. You can use wildcard in the file extension in file screen, but it prevents users from creating files of the specified types, not limits the file size. Maybe some third-party software can do this, or you may create a script to check the file size.
