After watching a video in a Web site, you may want to save the video file into your local disk for playing it offline in the future.
If the video file is stored in your browser's cache, this utility can help you to extract the video file from the cache and save it for watching it in the future.
It automatically scans the entire cache of Internet Explorer, Mozilla-based Web browsers (Including Firefox), Opera, and Chrome, and then finds
all video files that are currently stored in it.
It allows you to easily copy the cached video files into another folder for playing/watching them in the future.
If you have a movie player that is configured to play flv files, it also allows you to play the video directly from your browser's cache.

- Version 2.65
- Fixed VideoCacheView to detect YouTube videos from googlevideo.com domain.
- Version 2.63
- Fixed bug: VideoCacheView added YouTube split files with zero file-size, which sometimes caused the generated merged file to be corrupted.
- Version 2.62
- Added /cfg command-line option, which instructs VideoCacheView to use a config file in another location instead if the default config file, for example:
VideoCacheView.exe /cfg "%AppData%\VideoCacheView.cfg"
- Version 2.61
- For YouTube videos, VideoCacheView now displays your IP address at the time that you watched the video (The IP address is extracted from the URL)
- Version 2.60
- Added support for saving the new MPEG-DASH streams of YouTube as MP4 file that can be played on any media player. Requires to install
additional open-source software: GPAC.
VideoCacheView uses the MP4Box utility installed as a part of GPAC package to convert the MPEG-DASH streams into a valid mp4 file that can be played
with any media player. Special thanks to one of NirSoft users who gave me the hint for solving the problem with MPEG-DASH streams.
- Fixed bug with the cache of Internet Explorer (6.0 - 9.0): VideoCacheView failed to detect a small portion of the cache entries.

- Fixed issue with Chrome Web browser:
VideoCacheView loaded only 4 data files: data_0, data_1, data_2, data_3.
It seems that when the cache of Chrome is large enough, it starts to create more cache data files (data_4, data_5...)
Starting from this version, VideoCacheView will read these additional cache data files.

with IE10. If you don't do that, VideoCacheView may hang or crash...

VLC Media Player has the ability to play the entire merged .flv file, though it initially detects only the first fragment.
- Version 2.40

VideoCacheView doesn't require any installation process or additional DLL files.
In order to start using it, simply run the executable file (VideoCacheView.exe)
After running VideoCacheView, it scan the cache folders of your Internet Explorer and Mozilla browsers,
as well as the temporary folder of Windows.
Wait 5 - 30 seconds until the scanning process is finished, and the main window of VideoCacheView should
display all the video files that are currently in cache.
After the video list is displayed, you can use one of the following options, assuming that
the video files are stored in the cache ('In Cache' = Yes):
- Play Selected File: Allows you to play the video file directly from the cache,
assuming that you have a video player that is configured to play .flv files.
- Copy Selected Files To: Allows to copy the video files from the cache into another folder,
so you will be able to play them in the future.
If you have a video file that is not stored in the cache ('In Cache' = No), you can use
the 'Open Download URL In Browser' option (F8) in order to download the video file.
You can also use the 'Copy Download URLs' option (Ctrl+U) to copy the download URLs
to the clipboard, and then use then in your browser or in other download software.
Be aware that some Web sites may not allow you to download a video file in this way.
Flash Video Files In Temporary Folder
Each time that a Web browser plays a Flash video file, the .flv file is saved into the
temporary folder of Windows.
Normally, you cannot copy this temporary file to another folder, because the
flash player locks the file exclusively. Also the file is automatically deleted when you close the Web browser.
Starting from version 1.10, VideoCacheView displays the flash files in the temporary folder,
and allows you to copy them into another folder.
VideoCacheView can handle temporary flash files created by Internet Explorer, Mozilla/Firefox, Opera Web browser.
Be aware that you must wait until the browser finish to download them. otherwise, the copied files
will be corrupted.
Playing Video Files Directly From The Cache
Most Web sites today use Flash video files (.flv extension) for playing video inside the Web page.
VideoCacheView doesn't provide a build-in video player, but if you already have a video player that
is configured to play .flv files, VideoCacheView will be able to use it for playing the video files
directly from the Web browser's cache.
If you don't have a video player that can play .flv files, you may try one of the following freeware solutions:
- If you want to play/save files from the cache of Firefox, you must close all windows of firefox, because
only when you close them, Firefox saves the cache data into the disk.
However, if the current flash video that you want to save is still opened, you can copy the .flv from the
"Temporary Folder" entry, without closing any window.
- In Windows 7 - If you want to extract files from the "Temporary Folder" and UAC is turned on,
you must run VideoCacheView as administrator (Right click VideoCacheView and then choose "Run As Administrator").
For saving downloaded video files from the cache of the Web browsers, you can also run VideoCacheView without Administrator rights.
YouTube Web site started using MPEG-DASH streams instead of flash (.flv) files.
In order to convert the MPEG-DASH streams into a valid .mp4 file that can be played with any media player, you have to download
and install the following open source software package:
After you install this software, VideoCacheView automatically detect it and uses MP4Box installed as a part of GPAC package to convert the MPEG-DASH streams into a valid mp4.
If from some reason VideoCacheView fails to detect the installation of GPAC package , simply copy VideoCacheView.exe into the installtion folder of GPAC and run it
If you don't install the GPAC package, you'll get 2 stream files (One for video and one for audio): mpegdashtmp1.mp4
These files can be played by the media player of Windows 8.
Be aware that this feature doesn't work with Chrome Web browser, simply because Chrome stores the cache entries of YouTube as empty URLs, and thus VideoCacheView cannot detect them...
Copy all video files that are currently stored in the cache into the specified folder.
If you don't specify a folder, VideoCacheView will ask you to choose it.
Copy all .flv (Flash) video files currently stored in the temporary folder.
If you don't specify a folder, VideoCacheView will ask you to choose it.
/copymms <Source .dat file> <Destination .wmv file>
Convert a .dat file created when playing mms streams (Usually in the cache of the browser) into .wmv file that can be played by Media Player.
Start VideoCacheView with the specified configuration file.
VideoCacheView.exe /cfg "c:\config\vcv.cfg"
VideoCacheView.exe /cfg "%AppData%\VideoCacheView.cfg"

This command-line option can be used with other save options for sorting by the desired column.
If you don't specify this option, the list is sorted according to the last sort that you made from the user interface.
The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or
the name of the column, like "Content Type" and "Filename".
You can specify the '~' prefix character (e.g: "~Content Type") if you want to sort in descending order.
You can put multiple /sort in the command-line if you want to sort by multiple columns.
VideoCacheView.exe /shtml "f:\temp\cache.html" /sort 2 /sort ~1
VideoCacheView.exe /shtml "f:\temp\cache.html" /sort "Browser" /sort "Filename"
When you specify this command-line option, the list will be saved without any sorting.
