Windows 7: How do you redirect data from one directory to another?

How do you redirect data from one directory to another?

I am using a program that saves large files incrementally to my C:/ drive. I cannot change the location of where it saves these files. Since I use an SSD this is rather unfeasible as I'll run out of space quite quickly on this drive.

I am looking for an application that will automatically transfer (or initially save) the data to a different internal drive. However, the data must still be accessible via it's originally C:/ drive location. The program will only look in C:/xxx/xxx for the data.

Months ago I read up on something and I unfortunately cannot remember the name. It's basically a folder "loop", where the data appears to be in both folders at once, but in actuality only exists in the one folder. There's a way to set the folders up to act as such via command prompt. As mentioned though I cannot remember the name of this, and couldn't find it through google either.

Thanks and cheers!

In summary: Need data that is constantly generated on C to automatically end up on D yet still be accessible by programs fetching the data via C.

Hey, anyone? It's called "rooting" or "loop directories" or something but I can't remember 100%.

You need a directory symlink. Use the mklink command with the /D switch, i.e. mklink /D \source \target

What about MKLINK across mapped drives?


mklink /D c:\a_scans "c:\users\mxxxxx\pictures"

so now the "directory" a_scans will point to my pictures (a_scans has been used for centuries on other machines and many things point that way).


I try to access T:\a_scans
and I cannot.

I can access T:\users\mxxxxx\pictures without problem. I thought that mklink made a real directory entry.

Is this a permanent problem, or will it go away if I change DESKTOP to Win 7?

Please give the name of the program you are using...

Lot of programs have options wherein you may change the default drive/directory in Options/Preferences. It will be easier this way.

On DESKTOP, I can see all of the shortcuts that have been created with MKLINK, but when I try to access them, I get

T:\a_scans is not accessible

I was going to include an image but too much of a noob here to get it loaded.
