Hi

In a web application there is a document library and daily 1000 to 2000 documents are uploaded by users,

so here i want to calculate the average size of documents uploaded to this web application, so here i want to create a view based filesize column and apply filter on this column.

ex: filesize >500 KB

i did not fount filesize column in filter condition while i creating a view..i taken the 500 kb is for example. i will check in some range values like 500 - 1000 kb and 1000 - 2000 

You need to create a simple number type column and with the help of powershell update that column for the file size.

Hi,

By designer, The FileSize column is not visible in filter section of View. So you can create a custom view using SharePoint Designer by using CAML Query.

To create a view based on file size column, refer to the following post:
