  • How to remove password protection from compressed files

    - by Mehper C. Palavuzlar
    This has always been a problem for me for a long time. Let's see if any SuperUser can solve this: I have a directory in which there are lots of password protected .RAR files of which I know the passwords. I want to remove the password protection from all of them without extracting the contents. Since each file is larger than 1 GB, decompressing & then recompressing without password encryption is not a good option for me. How can I easily do that? I'm using WinRAR 3.80 on Win7. Any other 3rd party tools are welcomed.

  • I am trying to zip files individually, but the file type is unknown

    - by Jason Mander
    I am trying to zip some files with an unknown file type individually. I am using the following code in a batch script to do that: @ECHO OFF FOR %%A IN (bestbuy*nat*component.cpi*) DO "C:\Program Files\7-Zip\7z.exe" a -mx9 -m0=lzma2:d256m "%%~nA.7z" "%%A" The code will compress files individually ONLY if the file has an extension. Unfortunately the files that I have don't have any extension. In the code I am trying to zip files by doing a pattern match, the files are getting compressed into ONE file (which I do not want, I want each file compressed individually). Why does this code create separate zip files when the files have an extension (for example if I add .txt to the end of the files) and when there is no extension the code creates one zipped file. Can anyone please help me with the code to compress files with unknown file type so that each file gets compressed individually Your help would be greatly appreciated. Jason

  • BOOTMGR is compressed

    - by JavaAndCSharp
    So I've just finished messing up my computer beyond repair. I originally had a Windows 7 install on my 64GB SSD and all my data on my 1.5TB HDD. So I decided to install Windows 8 Consumer Preview. I tried to clone my 64GB SSD onto my HDD; but that didn't work either at first. I later learned that it wiped all my data off of it. Thank goodness for the cloud. So I retried the cloning after I realized that my data was gone, and I finished it. So I rebooted and got a cryptic error message: BOOTMGR is compressed. Press Ctrl+Alt+Del to restart. So I did. Several times. I followed the instructions to rebuild the bootmanager from many websites, including HowToGeek, smallvoid.com, and more. None worked. BTW, I've lost my Windows 7 Professional DVDs. All I have is my Windows 7 Home Premium DVD. It's the one I got with my laptop. How can I get back to a working computer? I'm willing to wipe anything, as my data is all in the cloud.

  • How do I convert a Linux disk image into a sparse file?

    - by endolith
    I have a bunch of disk images, made with ddrescue, on an EXT partition, and I want to reduce their size without losing data, while still being mountable. How can I fill the empty space in the image's filesystem with zeros, and then convert the file into a sparse file so this empty space is not actually stored on disk? For example: > du -s --si --apparent-size Jimage.image 120G Jimage.image > du -s --si Jimage.image 121G Jimage.image This actually only has 50G of real data on it, though, so the second measurement should be much smaller. This supposedly will fill empty space with zeros: cat /dev/zero > zero.file rm zero.file But if sparse files are handled transparently, it might actually create a sparse file without writing anything to the virtual disk, ironically preventing me from turning the virtual disk image into a sparse file itself. :) Does it? Note: For some reason, sudo dd if=/dev/zero of=./zero.file works when cat does not on a mounted disk image.

  • After Effects Question

    - by Josh
    Question here, not sure if it's the correct stack exchange site, sorry if it isn't. I have an After Effects project for school, and I've created a movie using JPEG sequences (10 @ ~100-200mb/each ). I have the output setting on the composition set to 640x480. I resized each JPEG layer via the fit to comp tool, but when I export the movie as a Quicktime movie, it is 1.1 gig for ~35 seconds of movie at 30fps. What am I doing so horribly wrong here?

  • Compressing with RAR vs ZIP

    - by FerranB
    A lot of people are compressing files with RAR, sending compressed files with RAR and so on. ZIP is more standard and works on all platforms. Windows users have ZIP included and linux users have no trouble with that file format. The tests I did sometime ago showed me that RAR compress better (some KyloBytes, no more) but not enough to use a non-free software when ZIP works on almost all the computers for free. Why do some people use RAR rather than ZIP for compressing?

  • Zero sized tar.gz file found inside a tar.gz file

    - by PavanM
    My current directory contains a single file like this- $ls -l -rw-r--r-- 1 root staff 8 May 28 09:10 pavan Now, I want to tar and gzip this file like $tar -cvf - * 2>/dev/null |gzip -vf9 > pavan.tar.gz 2>/dev/null (I am aware I am creating the zipped file in the same directory as the original file) When I run the above tar/gzip commands around 20 times, a few times I observe that the final tarred and zipped file pavan.tar.gz file has a ZERO sized pavan.tar.gz file. I am not sure from where is this zero sized file coming into the archive from. Note: I am NOT running tar/gzip commands on an already existing tar.gz file. I always make sure that the directory has only one file before running the commands On googling, as described here, I suspected that the tar.gz being created was also part of the file being archived. But in my case, gzip is the one who's creating the final file and by the time gzip runs, tar should be done tarring. This is happening on AIX but I've used Linux tag too, to draw more attention, as I guess the problem is platform independent.

  • How to compress .pdfs in word 2007?

    - by chobo2
    Hi I am trying to send my cover letter and resume away but apparently it is too big to send through craigs list(my computer says the total size is 500kb) as it has a 600kb limit(so small should be at least a meg). Hi there. You recently tried to email Some job Email, an anonymous craigslist address. However, your message was too big to be sent through our system. Craigslist has a 600KB limit on the messages we'll send. Please reduce the size of your mail and try again. Thanks for using craigslist. So when I convert my word 2007(.docx) files to pdf they become huge. Like they got from 32kb to 320kb. So is there a way I can either get around craigslist limits or compress my pdfs a bit to make it happy. I don't want to send zips and stuff since the person who gets it might not even know what to do. I rather not send .docx since not sure if will have office 2007 or the compatibility view installed and I rather just send it as pdf(as some place require it anyways to be in pdfs). Thanks

  • Compressed filesystem inside a file in Linux [migrated]

    - by Doc
    I have a flash drive which is FAT32 formatted. I want to put a linux filesystem on the drive inside a file. I know I can do this by creating a file and formatting is with ext3 (or any other file system) and then mounting it with the -o loop option. What I would like is that the above filesystem be compressed. Essentially something like a read-write squashfs. Is there something that exits that I can use? Additional bonus if the file can be stored as sparse, i.e. the file re-sizes as data is written or deleted.

  • Windows crashes when I try to compress large .MOV file from iPhone

    - by Andrew
    I have a 40 minute, 6 gigabyte .MOV file that I transferred from my iPhone to my PC. I need to upload the video to Youtube but the file is too large. When I try to compress the video, my computer will shut off when the process reaches 3 or 4 percent. This has happened in Windows Live Movie Maker, Riva FLV encoder, and VLC. Any ideas on how I can get this file down to a reasonable size so I can upload it online?

  • View/Find all compressed files on the server?

    - by Volodymyr
    I need to find all compressed files/folders regardless of file format on a Windows Server 2003 machine. Search options do not provide this capability. Is there a way to list/view all compressed files? Perhaps, this can be done by PowerShell using file/folder attributes and put into a txt file with file location. UPD: Under compressed files/folders - I mean files which appear in blue color in Explorer after changing file/folder attribute.

  • Create a zip file that doesn't create a folder when opened, Mac OS X

    - by MZimmerman6
    I am wondering if there is any way of easily creating a zip file that contains a bunch of files. However, when I double-click to open this zip file, I do not want it to create a subdirectory with the same name as the zip file, I just want all of the files to be extracted into the directory where the zip files is stored. Is there a certain flag I can add in terminal to do this, or any program that does this. Thanks for your help!

  • Extracting one file from archive: 7-zip requires decompressing entire archive?

    - by siikamiika
    I've noticed that when browsing an archive containing multiple files with 7-zip 9.20 Windows GUI, extracting one file for previewing takes significantly longer with .7z than .rar archives. With .7zips it also cycles through the filenames in the archive. To me it looks like decompressing the entire archive and keeping just one file. Is there a setting in 7-zip (current or beta/alpha versions) that allows RAR-like behavior?

  • Compressing and copying large files on Windows Server?

    - by Aaron
    I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

  • bsdtar : jcf and --use-compress-program-bzip2 produce different files

    - by Valerio Schiavoni
    These two commands produce files that are slightly different in size. In particular: tar --use-compress-program=pbzip2 -cf old_logs.tbz2 1tree_* 4tree_* 8tree_* The file old_logs.tbz2 is 100557548 bytes large. The command: tar jcf old_logs.tbz 1tree_* 4tree_* 8tree_* produce the file old_logs.tbz that is 98783046 bytes large. Where the difference in the two files originate from ? I'm using bsdtar 2.8.3 - libarchive 2.8.3 on mac osx 10.8.5.

  • Decompressing Files on an NTFS Volume from Linux

    - by amphetamachine
    I recently did something stupid on my dual-boot laptop, where I compressed the entire volume to make room for a Linux partition. For some reason, Windows let me compress C:\ntldr. Now I need to get it uncompressed in order for Windows to boot. Here are some of the operating restrictions I have: I do not have access to the BIOS. I cannot boot from CD/USB/floppy. (I installed Linux through PXE) It does not have network access. Is there were some way to specify that the ntfs-3g driver shouldn't compress files even if it thinks it should (if the directory is compressed) when mounting the volume? Or, is there a way to modify the attributes of a directory using ntfstools?
