What format is RAR and how do I unpack it? I’ve looked for downloads for my PSP but they are all in RAR format and I have no idea what to do with them once I download them. Happy coding.Ĭan you arrange for your file to appear in the back of the zip?ĭear Dave, I have a PSP and I love it, but there is a problem: I am confused about.rar files or documents. (I intentionally chose this silly format so that browsers would likely choose 'myfile.zip_a.jpeg' as the name in the download dialog when it appears.) Of course, how this is implemented depends on the server/language/framework and there may already be existing solutions that support a similar operation (but I know not). The request might look like: Which would mean extract - and return - 'a.jpeg' from 'myfile.zip'. Custom code can be deployed - then it is a rather trivial operation (in the scheme of things:) to map/handle a request, extract the relevant portion of the ZIP archive, and send the data back in the HTTP stream. However, if there is control over the server - e.g.
I think Sergei Tulentsevs idea is brilliant. But so is hacking in general:-) Another possible approach would be to build a custom server for that (see for more details). This approach is quite error-prone and is not guaranteed to work. The group consists of Chika Takami, You Watanabe, and Ruby Kurosawa. Happy End In The Near Future) is the second single sung by CYaRon!, a sub-unit under Aqours. If you succeed then you know file list and offsets, so you can proceed and get those chunks separately and decompress them yourself. So, using you could download part of file from the end (central directory is the last thing in zip file) and try to identify central directory in it.
Basically, this is a table that stores what files are in the archive and what offsets do they have.
(I need sudo because it seems FUSE is set up that way on my machine, you shouldn't have to need it) I'm aware that this is an old question, this is for others running into this problem.
Get/build httpfs: $ wget $ tar -xjf httpfs_1.06.07.10.tar.bz2 $ rm httpfs $./make_httpfs Mount a remote zip file and extract one file from it: $ mkdir mount_pt $ sudo./httpfs mount_pt $ sudo ls mount_pt zipfile.zip $ sudo unzip -p mount_pt/zipfile.zip the_file_I_want.txt > the_file_I_want.txt $ sudo umount mount_pt Of course you can also use whatever other tools beside the command-line one. Here's an example for Linux using, a very lightweight virtual filesystem (it uses FUSE). This way the unzip utility's I/O calls are translated to HTTP range gets, which means only the chunks of the zip that you want get transferred over the network. This is easy if you mount the zip file via an HTTP-backed virtual filesystem then use the standard unzip command on it. The trick is to do what Sergio suggests without doing it manually. Firmware, driver, and system software validated as a complete set (SPP) ensures updates are applied efficiently and correctly.
