Description: Enabling the "Register Copy Handler" option in TeraCopy Preferences causes severe graphical visual artifacts/corruption in the Windows 11 Explorer context menu (overlapping and pixelated text/lines). Additionally, right-clicking files while TeraCopy is running causes the TeraCopy application itself to immediately crash. Technical Details: Root Cause: The shell extension registered by TeraCopy under the System / Drag&Drop Handler category interferes with explorer.exe rendering and triggers an unhandled exception or crash within the active TeraCopy process when the context menu is invoked. Troubleshooting performed: System file integrity verified via DISM and sfc /scannow. Isolated via ShellExView: Standard Context Menu handlers were cleared. Disabling TeraCopy's specific handler under the System / Drag&Drop category immediately stopped the context menu visual bug and prevented TeraCopy from crashing. Unchecking "Register Copy Handler" in TeraCopy Preferences permanently resolves both the rendering corruption and the TeraCopy app crashes. Workaround: Unchecking "Register Copy Handler" while keeping "Add to Explorer context menu" active restores full system stability. Environment: Windows 11 Workstation / TeraCopy Pro (latest build).

Hi there. I am having issues with the latest version of Teracopy Pro. Every time I transfer a file from my iphone using LocalSend app to my PC via Teracopy, it fails. Teracopy prompts to accept the file transfer, which i select and then it proceeds to ‘download’ to my downloads folder. However, the file saved is 0 bytes. Says on my phone that transfer was done by in Teracopy keeps saying failed. Anyway, if you can please check this it would be appreciated. Thank you.

I’ve been having this issue for a long time. TeraCopy freezes randomly while copying files. My OS is Windows 11 for Workstations 25H2

I have been a long time TeraCopy 3 free user. Rarely if ever had issues. I jumped on the 4 Pro deal, have it installed. When I try to copy or move any files, it often takes 5-10 seconds for the file handler to display and start transferring. It is super laggy and is killing my productivity. I tried adding an exclusive in Defender. I am at a loss at what else to do.

I’m a big fan of the queue system on TeraCopy for Windows, but on Mac, it seems that the queue feature doesn’t yet exist. Would love to see this implemented!

It would be great to have an option to copy junctions to folders (as normal folders). I have many use cases where I need to implement junctions to mimic real folders. I imagine the best would be a 3-state option “Copy folders junctions): yes/no/ask. this is independent on the demand about copying junctions as junctions (even if it could be combined). I tagged this as an issue because it’s inconsistent between files & folders. Thanks

Past versions would always “instant” move files to the same drive, but now they are queued which isn’t necessary. I could increase the # of active jobs, but that also affects moves between different drives and I prefer to have those execute sequentially not simultaneously. Is there a way to change this back to the way it was handled in prior versions? Thanks.

I had been using teracopy v 4.0 for a few weeks and upon transferring files between SSD and NVMe drives crashes occurred so I removed v 4.0 rebooted and ran the installer for 3.17 which worked perfectly now I can no longer install that version as all folders needed have been removed

Request: Add the ability to display only selected levels of the folder hierarchy for a specific drive or volume in the File List. Reason: For example, if the File List contains one million files and two hundred thousand folders, it can be difficult to verify which folders were originally selected. It would be very helpful to have a way to display only a specific drive or volume and limit the view to a chosen folder depth, making it much easier to review the folder structure without being overwhelmed by the full list. Suggestion: Add a dynamic filtering feature to the File List that affects only how the list is displayed and does not change which files or folders will ultimately be processed, similar to the existing display filters (such as Removed and Moved). Users should be able to select a specific drive or volume and define how many levels of the folder hierarchy to display. For this purpose, it would be sufficient to show only the folder names (their paths), without listing the contents of each folder. But maybe an options to show files also...

Request: Add the ability to search for arbitrary words or phrases in the File List. Reason: For example when trying to locate a specific folder or file in the File List to delete it, it can be very difficult to navigate manually especially when working with a large number of files and folders. Additionally, the File List currently appears to update its contents in real time only for approximately four “pages” at a time while scrolling, making it even harder to find the desired location efficiently. Suggestion: Add a search box for the File List that supports both exact text searches and wildcard searches for more flexible matching. When one or more matches are found, users should be able to navigate to the next or previous search result, similar to the search functionality found in many text editors and file browsers. Thanks!

I believe this was available in v2? I was able to move a folder way down in list to top of the queue to process it before the rest. Used to come handy over a very large transfer job.

Am I the only one having issues with drag & drop not working in v4? I get a target folder not found/defined or something like that. I have tried with Directory Opus and Windows File Manager and neither work. I have tried a clean install. Right now I’m back to using 3.17. Still on Windows 10.

I have used TeraCopy in the past and have always appreciated its features. However, I stopped using it when the development slowed down to a crawl. Since Windows 11 offers decent copy and move functions, I managed without it for a past few years. Earlier today, I tried TeraCopy version 4.0.0.37 on my Windows 11, and I didn’t think I would say that as I was sadly disappointed when I quit using it, but was really surprised by how much the developer has improved and polished this incredibly useful utility. The file copying and moving works flawlessly, at least for me, which is what I’ve always relied on. What I truly love is the ability to create hashes for both small, large files or folders and verify them even weeks later to detect any changes, this feature is invaluable to me as I have at lest 500-600 terabytes of work files and folder that I need to keep healthy. I’m very happy to be back using TeraCopy, especially since I purchased the Pro version years ago and my key still works perfectly. Thank you very much to the developer(s) for maintaining such an excellent tool!

I would just like the option for the date to be appended to the folder name, so it would be “ New Folder With Items - 2026/07/26” or even just the date by itself for example, just something that would mean I don’t really ever need to rename anything lol. I tend to group a days stuff into a folder, and then put that folder into my organized group of folders on my server later and that can lead to me needing to go through and rename things so there aren’t any folders with the same names, because it’s in an upper level folder the folder itself doesn’t really need a name so I’m fine leaving it as is, but just this collision issue, but it wouldn’t happen if it had the date on it, IDK how useful it is for others though.

unlike past versions, the new version is clearing queued tasks instead of just clearing completed tasks. Is this intended? The previous approach was better imo.

TeraCopy currently relies on the Windows Explorer copy engine over SMB/local filesystem calls, which works well on LAN and reliable links but degrades badly over long haul or high latency/high packet loss WAN connections (satellite backhaul, cellular bonding, intercontinental fiber links, etc) Is there any plan to add a UDP based transfer mode (similar to UDT, Tsunami UDP, or QUIC-style approaches) for remote/WAN copy jobs? Even an optional transport mode for non local destinations would be useful for anyone moving large media files (video, RAW imagery, backups) across distance rather than just within a LAN. Wondering if this has been considered or planned for the future?

system wide setting to merge, rename, skip or prompt on folder collision on folder collision prompt, propose the above options, as well as retry if you want, but make sure single key press can select the action the user wants on folder collision prompt add the possibility & a checkbox to remember/repeat the selected action for all collisions in the transfer list

Hi all. I love my purchased copy of teracopy, but each time i make an update of teracopy V4, it changes a specific configswitch. In my case the configuration->shell integration->register copy handler->"false/true". The existing setting in the config is not respected by the update process. Each update it is set to “true”. Each time i have to set it to my prefered value “false”. Is there a way to prevent changing configflags while updating? BR.

This is a rare situation, but FYI teracopy has a bug where Windows Explorer copy and robocopy works fine. I have a file-and-folder backup created using Macrium Reflect 8.1.8017. If I mount the backup with a drive lever, windows 10 Win32_LogicalDisk reports the following about the drive letter: DriveLetter : L Provider : FileSystem Root : L:\ DriveType : Network FileSystem : Macrium tbFAT The Macrium tbFAT driver supports up to 3.9TB. However if I copy files from this source to an NTFS destination using TeraCopy 3.17.0.0 the transfer will complete and validate the checksums, but truncate files at 4GB as if the destination were FAT32. If I copy files using TeraCopy 4.0.0.37 it will copy the full size, but then either hangs during checksum validation or fails validation for file size mismatch reasons. And the copy operation is odd. It reports the files size to be copied as 4GB, but then for example if the file is actually 12GB, it continues copying until the file is 300% complete.
