Hi, I am currently using the File Manger module to quickly organize and distribute my files.  The problem occurs when I have a file larger than 2 GB, File manager refuses to display the large file in the module even after recursive sync.  I have investigated the problem and would like to know if my findings are correct and if it is possible to amend it to the next release of DNN.

In the database, in the table Files, the data type for the file size is int32 which is roughly 2Gig positive values.  Therefore, a file larger than 2GB will overflow the file size range.  I have also looked at the File manager source code.  In the function that adds file to the data table to be populate, the file size is also hardcoded to type int32.

I was wondering if the data type can be changed to bigint or int64  instead of int32.

Thank you.

are you using latest version? I remember a change from int32 to int64, but am not sure, whether it was for file size property

Hi,

I am using the latest version 5.4.4.  The first thing I did was change the data type of Size to bigint, in the db table, Files.  Afterward, I manually adding an entry for the 3GB file into the table Files.  However, when I navigate to the directory where the file is located via File Manager.  I would get an error saying the value is too small or too big for int32.  Afterward I went through the code and look at how the table Files get populated and locate where the filesize is parsed.

I wanted to make sure that there wasn't any residue from my previous modification, so I did a clean install of DNN 5.4.4 and the original table Files that gets created is type int.

I left out a little more information from the previous post.

DotNetNuke.Services.FileSystem  Class FileInfo has several functions that is used by Filemanager to populate the data table.  The function Size() returns type Integer.
