I recently came across a problem within a DFSR replicated folder where some files were not being replicated between the folders. After a bit of checking to make sure the file types were not on the excluded list I concluded that these could be temporary file after seeing this mentioned on a couple of forum threads.
Checking the files in explorer or using attrib.exe did not show any temporary attributes set, however checking with fsutil.exe did show a temporary attribute. The command to run is;
fsutil usn readdata "filename"
When I ran the command I got the following output;
PS L:\> fsutil usn readdata "Camera log.xlsx"
Major Version : 0x3
Minor Version : 0x0
FileRef# : 0x000000000000000000050000000e5dd6
Parent FileRef# : 0x0000000000000000000100000000011a
Usn : 0x00000002c60e7378
Time Stamp : 0x0000000000000000 00:00:00 01/01/1601
Reason : 0x0

File Attributes : 0x120

File Name Offset : 0x4c
FileName : Camera log.xlsx
The output here includes the file attributes on the file. The file attributes field is a bitmask that shows exactly what combinations of attributes have been set on the file in question. In my case shown here, 0x120 would be 0x20 (Archive) and 0x100 (Temporary) giving a bitmask of 0x120 for the file attributes.
Microsoft have an “Ask the Directory Services Team” blog post about this, listing all the possible values you can have in the file attributes field, but the short answer is 0x100 is the temporary value and if you’re bitmask includes the temporary attribute, then the file wouldn’t be replicated by DFSR.
If you’re looking to just remove the attributes for the file in question then the following command in PowerShell will do it;
Get-childitem ".\Camera log.xlsx" | ForEach-Object -process {if (($_.attributes -band 0x100) -eq 0x100) {$_.attributes = ($_.attributes -band 0xFEFF)}}
If you want to trawl any subfolders and remove temporary attributesfor more of these then you can use the following
Get-childitem .\ -recurse | ForEach-Object -process {if (($_.attributes -band 0x100) -eq 0x100) {$_.attributes = ($_.attributes -band 0xFEFF)}}
Or if you just want to do this in the current folder, just remove the recurse switch.
