RAR file size

Is there a way to determine how large a .rar file or multiple .rar files would be uncompressed?

If you’re using the WinRAR graphic interface: Open the archive (Double Click if you’ve set WinRAR to be the default Archive Handler), then Tools->Show Information (or ALT+I as a keyboard shortcut)

ETA: This is for a single archive. Gimme a sec to check on multiple.

ETA 2: Apparently this doesn’t work for multiple files. Selecting two archives and hitting enter opens two separate browsers. Going “up” in the WinRAR browser gives you a list of archives in the dir and allows you multiple selection, but won’t show the unpacked size for more than one at a time.

I’m using 7-Zip v4.65. I select all the .rar files and click on the info icon. On the bottom of the program, I see two number, one is the compressed file size. The second number is much larger. Would this be the uncompressed files’ size?

Sorry, I’m unfamiliar with 7-Zip; I’m afraid you’ll have to wait for someone who is to answer you…

I don’t know if this is what you’re looking for but with 7-Zip you can choose “test archive” and it will tell you exactly how large the file will be uncompressed.

With 7-Zip 4.65, just type the following, substituting the filename of the archive of interest:


7z l filename.rar

You will get a table showing the original and compressed size for each file, as well as the total:


$ 7z l bloodpak.rar
