| The Create button is disabled | No supported files may be selected, settings may be invalid, or an incompatible option may be active. | Add valid source files, check the output format and required options, and review any on-screen validation message. |
| My files do not appear after folder selection | Browser folder permissions, empty folders or drag-and-drop limitations may affect selection. | Try the explicit Add Folder control, choose a permitted directory and inspect the file list before creation. |
| ZIP output is almost as large as the originals | Most inputs may already use compressed media formats or the archive contains little repetitive data. | Use normal ZIP packaging and avoid expecting large gains; compress images or videos separately only when quality tradeoffs are acceptable. |
| The archive is larger than the input files | ZIP metadata, encryption overhead and incompressible input content can outweigh compression savings. | Compare total source bytes to final output and consider Store or lighter compression if available. |
| Creating the archive is extremely slow | Ultra compression, many small files, duplicate hashing or limited CPU power can increase processing time. | Use a faster preset, exclude unnecessary files and try a capable desktop browser for large jobs. |
| The browser runs out of memory | The selected workload may exceed practical in-page memory or Blob/output limits. | Reduce batch size, close resource-heavy tabs or use a suitable native archiver or documented API route. |
| The RAR option is missing from the local format list | True RAR generation is documented through the separate API rather than the browser-standard modes. | Use ZIP for broad compatibility or check the current API workflow for genuine RAR output. |
| My recipient cannot open an AES-encrypted ZIP | The extractor may support ordinary ZIP but not WinZip AES encryption. | Use a trusted AES-capable extractor, confirm the password and test a sample package with the recipient. |
| A password-protected archive reports the wrong password | The password may have been mistyped, altered in transit or used with an unsupported decryption engine. | Re-enter the exact original password and use a compatible extractor; verify the file was downloaded completely. |
| Filenames remain visible in an encrypted ZIP | Standard ZIP encryption typically protects member contents without hiding the central-directory entry names. | Use neutral filenames and avoid exposing confidential details in paths; choose a format with supported filename encryption if necessary. |
| Split archive parts cannot be opened | The numbered volumes are not independently extractable or a piece is absent. | Collect every part, preserve the original names and rejoin the set according to the displayed instructions before extraction. |
| A split archive fails after reassembly | Part order may be wrong, a file may be truncated or the reassembly command may have treated bytes incorrectly. | Check part sizes and sequence, use the correct binary-safe command, then retry and test the complete output. |
| An HTML self-extracting archive is blocked | Email gateways and browser security tools sometimes restrict active HTML attachments or scripts. | Share a standard ZIP or an approved secure link, and follow the recipient organization’s security policies. |
| Extracted folder names look incorrect | Character encoding or extractor support for Unicode filenames may differ. | Try a modern Unicode-aware extractor and inspect the archive on the target operating system. |
| Some files or folders are missing | Items may have been excluded, duplicate removal may have been too aggressive or browser selection may not have captured them. | Review the source selection and exclusions, disable risky deduplication and rebuild the archive. |
| An archive created from a URL has wrong contents | The URL might have returned an error page, redirect, authorization response or incompatible resource. | Confirm access and source type before importing, then inspect selected file names and content. |
| Compression mode does not save the estimated amount | Estimates cannot account perfectly for internal file patterns, metadata and encryption overhead. | Compare actual results and select a realistic compression preset for the material. |
| TAR.GZ extracts to an unexpected folder structure | The selected relative paths or top-level directory arrangement differ from the recipient’s expectations. | Reorganize the source files, create a clear root folder and test extraction into an empty directory. |
| GZIP does not preserve all selected files as separate entries | GZIP normally compresses a single stream, unlike multi-entry archive containers. | Choose TAR.GZ for a group of files or ZIP for common desktop sharing. |
| The download does not start | Browser download permissions, pop-up controls, storage capacity or interrupted output generation may interfere. | Allow downloads for the site, check local disk space and retry with a smaller batch if needed. |
| A received archive triggers a security warning | The package can contain risky executables, macros or scripts even though archiving itself did not modify them. | Treat the warning seriously, verify sender and content, and follow your security scanning policy. |
| Large archive output is corrupted | The browser may have run out of resources, the download may be incomplete or a volume may be missing. | Retry with fewer files, verify each part and test extraction before discarding source data. |
