Splitting Large Files Using 7 ZIP Command Line for SkyDrive / OneDrive

If you use SkyDrive or some other file sharing servicing, you may have realized that these services come with upload restrictions. SkyDrive is 2GB and Google Drive is 10GB (Microsoft are you listening?) 7zip, my favorite & free file compression utility, offers to split large files into multiple smaller ones based on a maximum file size.(Did I mention it is free?) This is real easy to do in the full 7zip software as shown below. Any files over 2GB are split into file.7z.001, file.7z.002, file.7z.003 (not their real names). You can later use the 7zip program to recombine them into one file or directory again. Right click the file you wish to be smaller so it uploads successfully & select Add to Archive. The specify in the Split Volume bytes field a value of 2GB or in the case of SkyDrive/OneDrive 1900M to be safe & below the threshold.

But how do you do this from the command line? Well with thanks to a little help from this link http://informationworker.ru/7zip.en/cmdline/switches/volume.htm we van now specify a maximum volume size in 7zip. Enter -v switch. Here is the syntax: -v{Size}[b | k | m | g] Here b is bytes, k is kilobytes, m is megabytes & you guessed it, g is gigabytes. So it could potentially look something like this 7z a a.7z *.txt -v10k -v15k -v2m. Just add a -v switch with a number and data measurement behind it. -v11k is 11 kilobytes before 7zip splits it. -v2g is 2GB before 7 zip splits it. Or in my case when using SkyDrive something like this. (Note: Skydrive/OneDrive does not like folks going over 2GB on uploads, so set yours to about 1900m to be safe.)

cd /D E:SkyDrive

for /d %%X in (*) do C:Batch7za9207za.exe u “E:SkyDriveArchive%%X.7z” “%%X” -y -mx9 -mmt –v1900m -we:temp


So now you can always have an archival copy of all your data on SkyDrive, but be warned, you may have a lot of split files to merge back together if you ever need to restore them.


Review of Acronis TrueImage Premium Backup Features

A Little Backup History:
I originally started out like most folks and backed up to a cd or flash drive.
Then online backup became popular.
More recently there are cloud file sharing services which serve as backups to a degree.
But what if all you items on the cloud drive become deleted?
And what do you do if you want to quickly recover from a HD drive failure or migrate to a new PC?
Can you wait three days for all your files to be restored and downloaded for three days grinding your internet to a halt?
Windows 7 built in backup was fairly straightforward, but what about Windows 8.1?
Or maybe the solution is to write yourself a nifty xcopy batch file

Then there is the need for syncing files on different PC’s. You can use Microsoft’s Sync Toy or use a Robocopy batch file.

Then the occasional need to clone an HD or that new SSD?

Well after years of trying all the free solutions, I purchased Acronis  Premium and am really impressed.
1. It has bare metal backup and recovery of data and system partitions.
2. You can also burn a rescue disc which lets you start recovery from any available media with a backup on it.
3. It supports network and USB drives.
2.It has file backup with all kinds of schemes from Incremental to Differential to Full with Incremental being default and supports versioning.
3. Since World Backup Day is coming up Acronis is giving away 250GB of cloud storage with a purchase. The online backup is seamlessly integrated into the software just like everything else. A cloud portal and phone apps let you access your files on the go. And the backup is fairly fast.
4. Acronis comes with a default sync folder which is shared by your three PC’s separately from your other  backup schemes. It is like a briefcase everyone can work out of. Also you can sync directories across the network as well. When directory A is updated Directory B receives the changes and vice-versa. This works nice for syncing two cloud storage accounts like Google Drive or Dropbox.
5. A lot of extra disc tools are included of which the most important is the cloning tool in my opinion. Clone to that new HD in a couple simple screens.

I am just really impressed. This really seems like a fully featured, yet “set it and forget it system”. Acronis TrueImage Premium provides multiple backup configuration, methods and  schemes to meet the needs of the majority of users.

Simple Media Apps for Windows 8 & RT

Hypertube- The Missing Windows 8 App?

This is everything you would expect from a YouTube App, especially since Microsoft & Google haven’t agreed on the Win 8 YouTube App. You can hide suggested videos and popular now and just see your subscriptions.

You subscriptions’ latest uploads show up nicely on the Live Tile & you have the ability to download and save video and audio for later offline use. While a little rough around the edges, all the functionality you need for simple youtube watching is here. Thumbs up to the developer! We hope they continue to develop this app.


Media Monkey

This is my favorite Windows 8 Media  player.

Tired of the big bloated Xbox Video and Xbox Music apps with tons of ugly ads? Try a nice simple Audio & Video Player & enjoy your own music and video file with a Windows 8 App experience.


MODERN.IE F12 Renders Page as Chrome, Safari or Firefox

Visit http://modern.ie

If you use Internet Explorer to browse the web or are a web developer there are a lot of neat tools to be had at MODERN.IE (even the occasional free Pizza.) You can download a VM browser of any of the major browser makers or try a free 3 month trial on browser stack.

Anyway for those uncooperative sites that refuse to work properly in IE try opening the F12 developer tools. Now you can re-render the page in whatever IE browser you desire as well as change the browser headers to match any of the major web browsers.

This could prove beneficial as well for the casual, but techie web surfer who comes upon a stubborn page.

For interest’s sake I used the first website that ever existed to demonstrate the functionality.


Archive SkyDrive with 7Zip

One of the down-sides of the new cloud sharing platforms is that you often don’t have a backup other than the recycle bin. (Dropbox does offer a PackRat feature.) I decided to do a little experiment with 7zip to see how I could create my own SkyDrive Archive.

  • First of all most of the cloud storage Giants have a file size upload limit, so we will need to break apart larger folders.
  • Download 7zip Command Line Utility.
  • Create a Folder Named Batch under your C:Drive.
  • Place the 7Zip Download file in the C:Batch Folder.
  • Also in the C:Batch folder make a new .txt document and save it as 7zip.bat.
  • Paste the following text in the 7zip.bat document:


cd /D C:UsersUserOneDrive
for /d %%X in (*) do C:Batch7za9207za.exe u “F:Backups%%X.7z” “%%X” -y -mx9 -mmt -wf:temp

  • Replaced the italicized   C:SkyDrive  with the path to your SkyDrive Folder.
  • The %%X  is a folder name wildcard. (So whatever the name is in the source folder, call it that in the destination folder.)
  • Save and run the batch file!
