If you want to delete some file on a Windows server or Desktop but you get the a dialog with an error saying:

"This action can't be completed because the folder or a file in it is open in another program"

windows-unable-to-delete-file-file-locked-get-what-is-locking-it-and-unlock-the-file-with-Unlocker-tiny-desktop-graphic-tool-0

Then you need to find out which Program is preventing the file from deletion / locking the file, I've earlier blogged on how to check which process locks file with tasklist or wmic Windows commands

However some users might prefer to not bother with command line check what is locking a file and then killing the Process manually with taskmanager (taskmgr.exe) but do both file unlocking from one single gui interface, that's especially for lazy novice users, gamers and most of Desktop Windows users.

If you're one of those lazy users you will appriace

Unlocker – a useful utility for unlocking files, it will help you figure out which file is using a file what program is using the file you're prevented to delete.
Unlocker is the tool for you if you get any of below error messages, when you try to delete a file:

 

  • Cannot delete folder: It is being used by another person or program
  • Cannot delete file: Access is denied
  • There has been a sharing violation.
  • The source or destination file may be in use.
  • The file is in use by another program or user.
  • Make sure the disk is not full or write-protected and that the file is not currently in use.

If you stumble unto an locked file once you download and install Unlocker tool and launch the tool ( in case it disappers in future a mirror of Unlocker tool here ).
Once installed if you click properties over the file which is refused to be deleted you will get a new menu such as in below screenshot:

NB! Beware while installing Unlocker you might be offered to install a bunch of malware (make sure you deselect it). Also Unlocker's site is made in a way so the Download button could easily be confused with some Google Adsense

Click on the file that is being locked and choose the Unlocker button, for example if you have a bunch of Videos installed and the video is being locked by VLC clicking on the file you will be shown VLC like in below screenshot

As you see you're shown the Process PID that is being used by the file the full path to the locking program and you have the option to quickly kill the process or unlock the file. Note that at some cases unlocking a file used by some critical program lets say Microsoft Word / Excel or OneNote could cause you a data loss, so before unlocking a file make sure you know what you're doing.

For more advanced users that still prefer GUI to find out what is Locking a file you can also check out Microsoft Process Explorer (advabced task manager) like tool.
If you haven't tried Process Explorer be sure to take a look at it as its a great tool for Win SysAdmins:

Process Explorer is very handy if you want to explore which .DLL (Windows Libraries) are used by a Process / Program

Fix audioCD play problems with VLC on GNU Linux

Monday, January 23rd, 2012

I've not played audio CD for ages. Anyways I had to set up one computer with Linux just recently and one of the requirements was to be able to play audiocds.
I was surprised that actually a was having issue with such as simple tasks.
Here is how i come with this article.

If you encounter errors playing Audio CDs on any Linux distro in VLC or other players, you might need to apply the following fix.

root@xubuntu-desktop:~# apt-get install xubuntu-restricted-extras
...
root@xubuntu-desktop:~# apt-get install ubuntu-restricted-extras
...

I'm not sure if this packages are required, anyways having them installed is a good idea especially on computers which will have to support as much multimedia as possible.

Trying to play a CD with VLC the result was not nice, you see in the picture above the error that poped up while trying it with VLC:

Due to wrong configuration of the play device VLC will be looking to read the audio cd from.

To succesfully play the audiocd invoke VLC command with a cdda///dev/sr0 argument like so:

hipo@xubuntu-desktop:~$ vlc cdda:///dev/sr0
...

To permanently fix the error you will have to edit ~/.config/vlc/vlcrc :

Inside ~/.config/vlc/vlcrc find the lines:

dvd=/dev/cdrom

Substitute the above line with:

dvd=/dev/sr0

Next find the line:

vcd=/dev/cdrom

Change the above line with:

vcd=/dev/sr0
Due to a bug in generating vlcrc , the dvd= might be set also to other messy unreadable characters (different from /dev/cdrom). This can also be the reason why it fails to properly read the disc.

If dvd= and vcd is set to a different unreadable characters delete them and substitute with /dev/sr0 .I've experienced this on Xubuntu Linux with a Bulgarian localization (probably the bug can be seen in other Linuxes when GNOME is installed in Russian, Chineese and other UTF-8 languages.

The strange error can be observed also in other players when the localization is set to someone's native language …
Alternative solution is to install and use rhythmbox instead of VLC.
Other program to play audio CDs called workman , you will have to get used to the interface which uses gtk1 and therefore obsolete. Putting aside the ugly interface it works 😉

Am I missing some important program?

How to take a screenshot of a game or Full Screen running program inside GNOME or KDE desktop environment on GNU / Linux and FreeBSD

Thursday, December 15th, 2011

Image Magick logo take screenshot of fullscreen running program with import on Linux / FreeBSD

I’m writting some game reviews and movie reviews, every now and then and therefore being able to capture a fullscreen running program like let’s say mplayer or vlc or some full screen running game is something I really need.

The usual PrtScr button which normally works to prepare screenshots in GNOME or KDE, however is not working if the root window handler is being passed to a different program than the Window Manager and pressing it while inside of many older programs or applicationsdoes not produce a print screen of the current screen.

Anyways I found a hack to this using the good old ImageMagickimport command line screenshotting program.

To take a screenshot of a certain program run from gnome-terminal or konsole using import cmd its possible to use a quick one liner which will take a snapshot of the root Window the started program will use.

Let’s say you want to make a screenshot of the entry screen of the FreeDOOM (DooM 3d shooter classical game arcade free Software Alternative).

Launch gnome-terminal or konsole , xterm , depending on the GUI environment you use and issue the commands:

debian:~$ ( sleep 15; import -window root my_desired_screenshot_name.png ) &
debian:~$ freedoom

The first command will launch import after a sleep of 15 secs and therefore will screenshot the active window which will be at focus after 15 seconds, where the & sign will background it and the second one will launch FreeDooM . You will have to wait for a certain secs and switch to the exact screen you will want to screenshot.
If you want to screenshot some game scene that will appear in 20 minutes change above sleep 15 cmd to be to something like sleep 180
That method can be used for screenshotting any other program running on fullscreen, the method is a bit inflexible as you will have to adjust a timing but it works fine 😉

How to play VCD videos in Debian Linux

Monday, September 26th, 2011

Totem VCD error occured, could not open location you might not have permissions to open the file

A friend of mine gave me a VCD with some coptic Orthodox Christian exorcism, where there pope was chasing some evil spirits from possessed muslims who came to the Coptic Orthodox Church in egypt. The video was made to be in VCD and as you can expect this did not worked out of the box with Totem and VLC out of the box.
Putting in the VCD video inside my cdrom poped up an error like the one in the header of the post.
In order to make the video play I had to use the old school and now a bit obsolete mplayer.
Hence in order to play the VCD on Debian Linux I had to install mplayer and w32codecs packages first e.g.:

debian:~# apt-get update && apt-get install mplayer w32codecs

Second to play the video from gnome-terminal, I had to switch to the mounted cdrom location /media/cdrom0 and launch the video with mplayer cmd like so:

debian:~$ cd /media/cdrom0/vcd
debian:/media/cdrom0/vcd$ mplayer vcd://2
...

In some cases it might be necessery to play the video with mplayer command like:

debian:/media/cdrom0/vdd$ mplayer vcd://2 vcd://3

Watching it with mplayer from console has some downsides as I couldn’t make the fast rewind work, but still it’s way better than nothing.
Too bad in Debian Squeeze 6 gmplayer is no longer installable. The gmplayer can probably be installed if mplayer is compiled from source, but I’m too lazy to try it out.
I’ve red also in some forums online that gxine is capable of playing the VCD play nice, but I couldn’t install it from my existing Debian repositories so I did not give it a go.

How to edit, convert, join, split and re-time movie subtitle files on Linux (Fix Subtitles bad timing) / Install subtitle manipulation console tools for Linux

Tuesday, April 19th, 2011

As a Linux user I sometimes face difficulties with watching subtitled, movies. I mostly use Mplayer, Totem or VLC to watch the common video files.
The most common problems I face with subtitles are caused by bad timing, many times the solution to the bad timing issues is very simpleand comes up to changing the default movie player I use MPlayer to VLC or Totem.

However at many occasions trying to watch the movie with different kind of movie player does not help.
In this dark moments I get seriously irritated I am not a regular Windows user, where such kind of problems are almost none as many of the Windows movie player problems does fix bad timing issues automatically.

Luckily there is a work-around to this subtitles timing issues and other mishaps caused by guys who created a Movie subtitle files with a Windows subtitle editor program, subtitles timing, the Linux work-around takes a few more minutes to install a package called Subtitles

The Subtitles text utility is written in Perl and contains two executables subplay and subs .

Subtitles is the Linux subtitle Swiss Army Knife as it is capable of convert, join, split, and re-time of subtitles files

Installing Subtitles tools on Linux is a trivial job and it comes to download and installation of the 2 perl executables.
Here is how:

1. Download Subtitles.tar.gz toolsI have mirrored Linux Subtitles (Subtitles.tar.gz) here originally the binaries are to be found on URL address: http://karasik.eu.org/software/ , issue the commands:

linux:~# cd /usr/local/src
linux:/usr/local/src# wget http://www.pc-freak.net/files/Subtitles.tar.gz
...
2. Unarchive it

linux:/usr/local/src# tar -zxvvf tar -zxvvf Subtitles.tar.gz...
linux:/usr/local/src# cd Subtitles-1.0

3. Compile and install Subtitles system widePitily the Subtitles tools are not currently available as a packages in the repositories of Debian and Ubuntu Linux and thus easy installation without compilation via apt-get is unfortunately not available.

Here is the commands with which to compile and install Subtitles:

linux:/usr/local/src/Subtitles-1.0# perl Makefile.PL
...
linux:/usr/local/src/Subtitles-1.0# make
...
linux:/usr/local/src/Subtitles-1.0# make test
...

All tests successful.Files=1, Tests=17, 1 wallclock secs ( 0.05 usr 0.00 sys + 0.06 cusr 0.01 csys = 0.12 CPU)Result: PASS

linux:/usr/local/src/Subtitles-1.0# make install

Installing /usr/local/share/perl/5.10.1/Subtitles.pm
Installing /usr/local/man/man1/subplay.1p
Installing /usr/local/man/man1/subs.1p
Installing /usr/local/man/man3/Subtitles.3pm
Installing /usr/local/bin/subplay
Installing /usr/local/bin/subs
Appending installation info to /usr/local/lib/perl/5.10.1/perllocal.pod

Now as we have the subs executable installed, Let’s say your movie subtitles displays 5 seconds earlier before the movie scenes (bad timing), all you need to do to adjust your subtitles to show up in correct movie scenes is issue:

hipo@linux:/home/hipo/Movies$ subs -i -b 5 your_movie_subtitle_file_name.sub

now check out the subtitle files once again with your favourite player and the early subtitles display on your movie should be fixed.
Let’s have another scenario, say that your movie file is encoded to display 24 frames per seconds (fps) but the subtitle file is created to display the subtitles for a 25 fps, to solve this situation issue:

hipo@linux:~# subs -i -a 24/25 your_movie_subtitle_file.sub

Another possible scenario where subs command will be a precious asset is if you for example want to merge two subtitle files into one.Let’s say you have subtitles for a movie which are split over in 2 parts and the corresponding subtitles are in 2 different files, but eventually you find a better quality of the movie (DVD quality) in a single file and therefore you need the movie subtitles to be stored in one single file.
In that case to merge the subtitle files from let’s say the files movie_subtitle_file1.sub and movie_subtitle_file2.sub use the command:

subs -z movie_subtitle_file1.sub movie_subtitle_file2.sub

Some few other helpful things you can do with subs on Linux, are for example: splitting a file after a determined period of time, separating overlapped lines, and joining files into a single subtitle.

If you want to remove all the comments of gestures, facial expressions loud laughing etc. which displays usually the annoying (‘[Sneezing]’ or ‘[Music playing]) during the movie screen play, issue:

subs -e 's/[s-]*[.*]s*n*//gs' movie_subtitle_file.sub

Also other interesting Linux tool which is useful if you want to make conversions between subtitle in a (.sub) format to (.srt) format is called sub2srt perl script:

sub2srt’s home page is located on the URL address: http://www.robelix.com/sub2srt/, just to ensure it won’t just disappear with time I have created sub2srt mirror here

The most basic usage of sub2srt linux converting tool is by simply passing input sub and output srt file names like so:

linux:~# ./sub2srt 5rFF-pop.sub 5rFF-pop.srt

sub2srt supports changing of fps rate per second during conversion with the -f option as well as creationg of converted files in dos like end of file (CR+LF) with the –dos option.

Hope this article makes sense. If you find it useful, please drop me a thanks comment 😉
