Hi,

I am not sure but can you check with CDir?

hello,


one possible is to count all files' size together under this folder.

To count all file size will takes too much time cause the targeting folder is tree structured.too many folders and files are there.recursively get all files and count their size will takes a little bit times.

In CDir, i still dont find any api for get folder size.

Thanks in advance.

Hi,

You have to scan (by CDirScan and CDir, for example) the folder hiararchy and get each individual file size then sum them up.

"Using CDirScan"

You are right the calculation can be time-consuming so you should split the task with Active Object

"Splitting long running tasks with active objects"

and for better user experience you can also show a wait dialog during the scan.

Hi all!
Please help me, how to estimate time of calculating size?

Thanks.

If you mean that you want to display a progress bar, you may rather want to use the number of files, than some estimation.
