Just for some additional info,

I set the file variable to nothing and retried... same issue.
I get through the first 150-200 data files with no problem but it eventually
comes to a screaming halt when the Excel Memory in Task Manager gets over
60-70MB.
In the beginning, it can scan a file in 1/2 second
by #225, it takes about 5-10 seconds,
It's on 254 now with Memory at 94M and it's
about 22 seconds a file.
CPU Usage is always pegged at 50% (Dual Core processor).

If I remember right, at some point over 100MB Memory it actually seems to
speed up....

Thanks again,

I have another routine that puts the datafilenames in an array: arrFiles
This routine is called in a loop that goes through all the datafiles.
It's passed the file number open, read into an array (arrMaster), then data
file is closed.
the arrMaster, gets cleared and resized each time a new file is open.
The array is then used, and the process is repeated until all the files have
been used.

Thanks again for any help,

Hi,
I have a VBA project that opens many files, extracts info, then closes them
(between 10 & 500 files sequentially).

I open the data file, get what I need, close it, then open the next data file.

The files themselves are all pretty small - each under 60k.

However, as the application cycles through all the files, the memory usage
in Task Manager keeps growing and the app slows down.

I've checked in VBA Editor after it's done and it shows all the files that I
opened and closed.

Can someone show me an example of the proper way to handle files so that the
memory is actually released back to the system?

Thanks!
