Ideas / Checksum validation?
« Last post by N0_W4RN1NG on July 28, 2021, 08:30:08 am »
Hi,

I just found out about the copy handler project and replaced teracopy, and I am very happy that I did.

One feature that copy handler lacks compared to teracopy is checksum validation of files, and it would be very useful to have that as an option to show that in the windows explorer context menu.

I thought that perhaps this was not included because it's not strictly in the domain of copy handling, and the job of validating checksums should be left to a dedicated application, and because I'm new to the project, I decided not to create a Jira ticket for this until I can confirm.

I think checksum validation can be useful when copying files from ftp servers, network drives, and removable USB medias for a few reasons: 1.) to verify file is not corrupted, and 2.) to verify that the file is the original untampered version 3.) to help the user decide if they want to copy/use it. It can also be useful to the user in general.

I'll throw in a couple of possible ways to implement this, but others may have better ideas:

1. Add context menu within each of: (CH) Copy/Paste/Move/-> Verify Checksums then Move. Pop up window with table of file names and columns to input checksums. (Unsure about Special copy/paste/move since I haven't been able to get those working)
2. Add a column next to the file names within the Status window where the user can paste checksums so that they are verified before/after completion.
3. Add context menu just to validate checksums.

Thank you for your time and consideration! I love this project.

Thanks for the suggestion. Something close started to appear in CH 1.50beta1 (although is only partially implemented). You can define a feedback rule to automatically retry when an error is encountered.
It does not allow to specify retry interval though and currently is only available in "Enter copy parameters..." dialog box and in task definition files.

Is it slow when reading or writing to usb drive?
Currently CH write speed might be limited by the way it writes data to a file.

It seems like somewhere in the release process version was not bumped to 1.46. For now I've implemented a workaround that does not need creating a new build.

I tried this link:
http://www.copyhandler.com/en/request-a-feature

It displays the menu, but is otherwise blank.

I googled "copy handler request a feature" and found this link that works:

Ideas / Automatic Retry with configurable interval
« Last post by ajw625 on June 17, 2021, 05:48:49 pm »
I started a copy operation yesterday that Copy Handler estimated would take about 20 hours. The copy was to a network share in another location, over internet, so it was a bit slow. For some reason the copy operation had an error in the middle of the night and it sat there waiting for me to click "Retry", which I did in the morning, and the copy continued.

It would be great if you could add an Automatic Retry option and allow the interval/frequency of retries to be configured in minutes or seconds. My suggestion would be to have this feature enabled by default with an interval of 5 minutes.

I am trying to find a way to enhance the performance of my USB stick.

It currently starts at around 60-300MB/s with the default Windows copier, then it dips down to 7-10MB/s for large files.

I read online that it is caused by the buffer getting filled then it just works without the buffer.

I don't have the feature as suggested on the driver to enable write cashing. So it is  a limitation from the Hardware.

I did try this program and a few settings but it just stays at around 5-8MB/s. The speed did not go any higher than that.

Is there a way to use the program to overcome this issue so that it keeps clearing the buffer and it works at maximum speed?

Hi Ixen,

the updatecheck seems to check against the wrong build number.
The latest stable is 1.45.1048.0 from 2020-12-24, but it wants to have 1.46.1048.0 from 2020-12-24 in stable or rc channel.

See picture.
