saving user's search path

i need to save the path that the user takes to select files. let's say i prompt the user to search in Desktop. but then in the search window they go to Documents/testfolder/anotherfolder/filename.txt or something similar. how can i save this path, so that when i need to parse the data, it can open it? i keep getting an error that says that my filename does not exist, so i'm assuming that is my problem.

You can use uigetfile or uigetdir function

[Joseph Cheng]

if it is inside a GUI at the start of the program define a variable CurrentDir or something similar and assign it to the default folder (in your example desktop or maybe c:\).

This way instead of hard coding the default folder you leave it as the defined variable CurrentDir inside uigetfile or uigetdir. Then when they navigate away save the returned directory as the CurrentDir. This way when it gets called again CurrentDir is replaced with the folder they were in.

I hope thats clear.

if it is inside a script *.m file you may need a check at the beginning of the script to see if CurrentDir is defined. If not then set to Default folder.
