Error occured while uploading file in Deployment solution 7.6 OS Files

Hello

We trying to upload windows 8 and 8.1 souce files in Deployment solution 7.6 OS Files but it giving error that Error Occured while uploading files.

I found one article TECH216785 but still there is no change.

Problem is, the original Windows 8 and 8.1 sources\sxs folder contains files with very long names and together with the package path they exceed the maximum length allowed.

I tried to fixed it using a sources folder without sxs subfolder and copied it to the package via NSCAP share later but again while copying sxs folder it giving error for maximum length file name issue.
