Folder sensor - Cannot access folder: The folder doesn't exist (code: PE032)



I can only get the Folder sensor to work on probes, when ever I try to add a Folder sensor to a Device that is NOT a probe, PRTG cannot access the folder.

Have not had an issue with other Sensors, even the WMI sensors are all working ok (CPU Load, DISk Free etc).

- Tried changing the security settings - Added user "Everyone" with full rights to the folder. - Tried sharing the folder. - And tried on multiple devices. But always get same error. { Folder sensor - Cannot access folder: The folder doesn't exist (code: PE032) }

Any ideas?

The folder sensor needs an UNC path starting with a share on the target computer. The UNC name of the target computer has to be omitted as it is automatically taken from the sensor's device.

Let's say you want to monitor the temp folder on the C: drive of your target computer. You'll have to enter C$\temp as path.

Paths beginning with C:\ would always refer to the C: drive of the probe computer, independent from the device the sensor is situated in.

OK, that means, if I have a shared folder named "datas\folder" and is letter is "F", I have to configure "F$\folder"

What about Linux machine, if I have a SMB shared folder "/datas/folder", what should I configure ? I try "/datas/folder", "folder", "/folder"....All not working

Any advice

It depends how the share is defined and maybe "mounted". Please also try the Share Disk Free Sensor. And also see the tips in the following KB article for Troubleshooting Share Monitoring with PRTG.

I have created an share with "Map Network Drive"\Data\Backup. It is an folder on an QNAB (NAS) Drive. I get this share: Q:\ on the Server. If I use Q$ on the FolderSensor it just say "code: PE032" What shout the Paths then be ?

Best regards - Jan

If the folder is mounted directly, you should be able to use q:\ as the path.

Just a note to all having trouble accessing a folder with a sensor. (error PE032)

We also suddenly were unable to monitor the Spool folder of a new print server like we always have on the previous print server and received PE032 errors.

I could access the
without issues from other servers/probes and the account used in PRTG had full access rights. (on the new server, oddly enough
did also not work)

When I created a Temp folder on E:, like we have on C:, I could also not access it. When I changed the sensor to monitor the Temp folder on C: instead (so C$\Temp) we had no trouble accessing it and the sensor went green.

Change it back to E$\Temp and the sensor errored out again...

Finally I was able to solve this (or work around this rather) by changing the Spool folder hosting Server settings in PRTG to use the FQDN rather than the IP address in the "IPv4 Address/DNS Name" section and the same in the "Service URL" section. No more errors after that.
