Problems creating archives

Paro, Paula [CMPS:2721:EXCH] — Fri, 27 Oct 2000 12:26:37 GMT

Hi,

I have a VI that create test reports. The name given to these test reports
is created concatenating an identifier (that is the same for every test) +
date + test time. However this test is performed many times during the day
and about 50 archives are created with different names (different times) in
the same directory.

So, I'm facing the follwing problem: when I have a determined number of
those archives the program indicates that the path is invalid and I have to
delete all the past archives and then the program works well again.

I'm using LabVIEW 5.1 and a W95 system. Is there a limit of archives that
begin with the same characters ? The identifier field has 5 characters that
are common to all the archive names.

Does
someone know something that could explain this problem ?

Thanks in advance for any help.

The limit is win95 and FAT. I don't remember the exact number, but a folder
can only have so many files. The best thing to do is to upgrade to Win NT
and use NTFS but you should still periodically purge old files.

The only limitation I am aware of is in the C:\ directory
you can only have like 128 files (subdirectories).
In a subdirectory Like C:\temp you can have as many files as the hard disk will hold.

The FAT should be FAT32.

I often save data in that same manner, and I haven't run into any
restrictions as to the number of files or archives that can be saved in
a directory. I guess my first concern is that you get an "invalid path"
error. Is it possible for you to see (through LabVIEW highlighting, or
an indicator on the front panel) what the path is when this error
occurs?

When you delete the files, are you stopping the program and starting it
again? I'm just wondering if something in the code creates the error,
and you clear it when you stop the program and start over.
