One of the new surprises to be seen in the App-V 5.0 Beta is that the old SFT format is gone, replaced by an AppV format.\u00a0 So what’s up with that?<\/p>\n

The SFT format was created for the original SoftGrid product in order to support the groundbreaking file system we created to support streaming on a block, rather than file, basis.\u00a0 This file system, which we called the “Jigsaw” file system internally, was unique from any other file system due to this feature.\u00a0 Most of the Softricity patents were based around this file system and it’s usage.\u00a0 Any other file system, CIFS, NFS, and others, could only remotely copy entire files, but this file system could bring over portions of files on an as-needed basis.\u00a0 To make use of this unique feature, we needed a file format that presented these blocks to be streamed, and this was the SFT format.<\/p>\n

In the App-V 5.0 Beta, Microsoft has removed the Jigsaw file system, as exposed by the Q: drive, and thus also chose to eliminate the SFT format and replace it with a new AppV format.\u00a0 I think that this effectivly eliminates block level streaming, but I stopped being a fan of that feature many years ago, so big loss there.\u00a0 So just what is this AppV formatted file?<\/p>\n

Basically a compressed folder.\u00a0 After sequencing a new package with the 4.0 Beta, I made a copy of this .AppV file, and renamed the file extenstion to .zip.\u00a0 Now I can browse and look into the APPV file.\u00a0 I’m not sure if I can make any changes here, as it might be based on a compressed format with something special that I might break by saving a change, but at least I can look around.\u00a0 Here is an example:<\/p>\n

So since the SFT format is gone, does this also mean the end of the 4GB limitation?\u00a0 You betcha!<\/p>\n","protected":false},"excerpt":{"rendered":"
