Could I put programs on external hard drives?

by rohan.katipally-208132649 / February 13, 2006 4:01 AM PST

Could I install programs on external hard drives, for example like Microsoft Office or things like that> I don't mean like an entire OS, but just programs.

I don't recommend it.

Is this for a laptop or desktop ?

For a laptop.

I am running out of HD space, and I thought that an external HD would be more efficient than an internal one because then I don't need to put my current internal HD to waste. But if my internal HD's space is still taken up by programs I install on my external HD, then I guess its a waste.

How large is the current laptop HD ?

Why not get a bigger laptop hard drive ?

A better solution would be to reserve your laptop hard drive

external HDD for using the OS
by videolabs / February 20, 2006 12:07 AM PST
In reply to: Yes but . .

I thought I can use the Licensed software in single HDD external so that when I keep moving to office and home the same OS can be used.
Besides it offers security and no one else can use my lap top or desktops.
What do you think can be the drawback?

Just one thing. No Windows does this.
by R. Proffitt Forum moderator / February 20, 2006 12:17 AM PST

Windows on USB or Firewire can't do this. Applications, since they put items in the OS registry will then fail to run from the external hard disk.

Maybe in this case, Windows is the wrong OS since what you asked for, has never been seen.

Same response as stated but also
by Steven Haninger / February 13, 2006 10:24 AM PST

not all of the program will go on the external. Some will be in Windows folders anyway. You will not be able to run these program on another PC if that's what you have in mind. Also, if the external is turned off or unplugged, you might experience some error when Windows starts or searches for data. Not a good idea IMO.

wow,,, you guys need to stop and think!!!!!!!!!!
by Alexander myi / August 24, 2015 7:39 PM PDT

this is not true the file or app has a .exe and .dll files all of which can be ran and placed on a external device with no problem but your problem lies in one simple area your temp, appdata and even your system 32 for you Microsoft office it places all its files throw out your os this meas that when it down lode it down lodes it dlls and exes in your os and in hidden places all over your computer and those can be moved into your os but it is agenst the law to modify there dlls or exes and if you move all those files they will still wound to start were they were and if moved there not were the exe calls for them so you error and you would have to modify the exe to tell it were they are now the reason Microsoft dose this is because they don't wont people to steal and crack there software.Now you can put your apps on your flash drive throw all you have to do is have all the files from program data in a folder and run the exe.this being sayed they are making this hard on you now and slowly but shely you have to be more skilled to do so but if your never going to tack the usb out simply murge your c drive with your hardrive they will become one hardrive so they work together then it will work with no problems.

by dillon45 / February 16, 2006 6:12 PM PST

of course you can, I have several myself an external is little different to an internal, I am presuming you are talking about a pc, but even with a laptop it works fine though you do need a little more care

There are two types of programs...
by gagapkm / February 16, 2006 6:43 PM PST

...that work well when operated from external media:

(1) Freestanding Windows programs (i.e., those which need no *installation* or *uninstallation* rocedures...usually these will be small utility programs, and often they will be freeware).

(2) Well-behaved DOS programs (i.e., those which use the DOS services to access hardware functions) also still run under Windows. However, they may not have originally included mouse support and/or support for printers that require API access (i.e, the printers sold today).

I keep a number of these on a USB flash drive, ready to use on whatever computer I am using at the time.

MS Office = NO!
by royc / February 17, 2006 2:12 AM PST

but all of the data files can be put on the external drive. The same applies to most other programs.

MS Office for Macintosh = YES!
by Apta Good / February 17, 2006 7:21 AM PST
In reply to: MS Office = NO!

If it's MS Office for Macintosh, the answer = YES. There's no installer needed; just move the MS Office folder found in the Applications folder to your external hard drive.

definitely Yes!
by eduardo01usa / February 20, 2006 12:37 PM PST

I`ve saved a lot of different programs in my MAXTOR external drive (BIG PROGRAMS),like Microsoft fligh simulator,Autocad 2004,Adobe Photoshop,and Games like Falcon Allied Force,Jetfighter V Homeland protector, Pariah etc. All of them work great,but don`t forget your external drive must be ON. Good luck.

Agree BUT!!!............
by cm2gj / March 4, 2006 9:05 AM PST
In reply to: definitely Yes!

Agree. Not the OS, but any other software can be installed in an external hard drive. One thing must be know is every time you disconnect and connect the USB drive you take a risk. Windows can give you a different letter to your drive and this can ruin your life!!!

For example, if you have a pc with a C hard drive and D cdrom drive. You add an external hard drive. Windows assign the E letter.

If later you remove the E drive, insert an USB drive and later the USB hard drive, windows can provide the USB drive letter to your memory instead of your hard disk, and this can be a big problem.

That might depend on the game and the way they programmed it. Why not try it with the games you're interested in?

...I will. I've been having most of the extended packages of the Sims 2 for a while but had to stop playing because it was just too slow due to lack of harddrive space. Now I got a 500GB external hard drive so I wanted to test them out. I wanted to be sure before I messed up the programs.

fore the most part a cd game is a installer and the exe checks for the cd to start this is so you cant down lode the game save to flashdrve then sell the cd.but that can be fixed in the security settings.

In reply to: definitely Yes!


I want to add similar programs so that I can essentially have a mobile desktop when i travel from office to office. what has been your experience with intensive programs like Autocad 2004, Adobe Photoshop, Microstation XM running via an external hard drive? what is the process for loading these types of programs? Is there a need to load an OS as well?

RE: Could I put programs on external hard drives?

Would it work better to create a virtual machine on the external hard drive (with a program such as Microsoft's Virtual PC) and install and run your programs through the VM?

Collapse -
yes you can just be careful
by eonward / February 22, 2013 6:04 AM PST

@dangre, that is probably the best answer I have seen to this post. Put all your programs that you can't fit on a virtual drive, no problem, then to take it a step further you can put the virtual machine on the external drive. (Unless you can access your virtual machine on any computer with internet.)
Yes you can put programs on External Hard Drives but you have to carefully put the program on there and some folders go certain places whether its a internal or external but this saves space. Sometimes you may have a program starting a file, it may say it can't find a certain folder, file or the program. Be sure when downloading or installing programs to change the folder given.

its easer then that
by Alexander myi / August 24, 2015 7:52 PM PDT

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
