If you have never come in contact with .srr files before you are probably wondering what those files are used for. You may find them attached to downloads on the Internet, for instance if you download a rar archive via torrents or files from the Usenet.
You may also wonder if they have a similar functionality as parity files or are used for a different purpose. When you try to open srr files on your system you will receive an error message that the file type is unknown, and that there is no associated program installed on the system.
Using the web service to find a correct program for the file type reveals that the service does not know the file type either.
Lets take a closer look at what srr files are used for and which programs there are available to make use of their functionality.
A Rescene file contains information about how a rar archive is structured, and may even contain additional file types like nfo or sfv. The main purpose is the option to recreate the original rar archive from one that has already been unpacked to the system. Say you have downloaded a movie that was packed as a rar archive from a torrent and unpacked it after the download to your computer to watch it. Later on you realize that your sharing ratio dropped to a point where you are not allowed to download anymore, or notice that there are no seeders left to distribute the file further. If you still have the rar archive on your computer, there is no need or purpose that the srr file can fulfill.
If you have already unpacked the release, and suddenly realize that you need the rar files again, for instance for distribution (seeding) purposes, then you can make use of the file to recreate the rar archive in its original state to distribute it. The file can come in very handy if the seeder count dropped to 0 for a particular file that is still popular.
Most Internet users will probably never come into a situation where they need to recreate a rar archive for distribution purposes.
The original website the ReScene Pack software was published on is no longer available. But there are mirror sites available where you can download the applications from. Applications? Yes, there is a command line version and a graphical user interface version that you can make use of. Both versions of ReScene can be downloaded from this website.
To create an srr file from the command line, you basically put the srr.exe file into the same directory as the sfv file and the rar files and run it from there with the sft file as an parameter, for example srr test.sfv. The program will echo error messages right in the command line window. If no errors are encountered, an srr file has been created.
The graphical user interface version works similar. Click on select .sfv of the release to pick a single sfv file or make use of the batch modes instead. The process itself should not really be that difficulty provided that all files are in their correct folders. All command line options provided by the command line version are available here as checkboxes.
To recreate a rar archive you need to load the srr file instead. If you are working with the command line, you basically need to point the program to the srr file and have all the relevant unpacked files in that folder structure as well. Please note that all files need to have their original names. If you have renamed them in the meantime, you need to rename them before you can recreate the archive. The process is similar if you are using the user interface version instead.
You can display all parameters by running the program without parameters:
ReScene .NET 1.2
Usage: srr filename [switches]
To create a reconstruction file (SRR), use the release SFV or RAR file.
All files referenced by the SFV must be in the same folder as the SFV.
ex: srr example.sfv -s *.nfo -d
To reconstruct a release, use the SRR file created from the release.
ex: srr example.srr
-l: List SRR file contents only.
-x: Extract SRR stored files only.
-d: Use parent directory name as basis for generated .srr file name.
-p: Store file names with paths (relative to the input base directory)
-r: Attempt to auto-locate renamed files (must have same extension)
-u: Disable automatic CRC checking during reconstruction.
-y: Assume Y(es) for all prompts.
-v: Enable verbose (technical) output.
-s : Store additional files in the SRR (wildcards supported)
-i : Specify input base directory.
-o : Specify output file or directory path.
-h : Specify alternate names for extracted files.
ex: srr example.srr -h orginal.mkv:renamed.mkv
Srr files are specialized files that the majority of Internet users will never come into contact with. I hope this guide helped those who did come into contact and could not figure out what to do with those files, and whether they were needed at all.
