Avoid overwritten files

Extract files without overwriting your work

For a ZIP you can open in Windows, the simplest approach is to extract into a new, empty folder and compare the files before merging them with your work. If you must extract into an existing folder, check the conflict setting first. Skip, Rename and Overwrite have very different results.

1. Give this extraction its own empty folder

   Create a new folder for this attempt and confirm it is empty. Use a name that distinguishes it from earlier extractions, such as client-assets-review. Keeping the incoming files separate lets you compare them before they reach a working project. Back up important work before deliberately merging files into it.

2. Point the extractor at that folder

   For an ordinary ZIP in Windows, right-click the ZIP, choose Extract All, and set the destination to the empty folder. Read the whole path before continuing. If the proposed folder already exists, do not assume it is empty simply because its name matches the archive.

3. Stop and read any replacement choice

   If a file conflict appears, pause. Choosing Replace can overwrite the copy already at that destination. Choosing Skip omits the incoming colliding file. When you expected an empty folder, cancel and check the destination rather than applying a choice to every file without reading it.

4. Compare before you merge

   Check the extractor's result, then review the new folder. A matching filename does not mean matching contents. Copy only the files you intend to keep into your working folder, making any replacement decision at that point. Keep the archive until you have checked the files you need.

What EasyUnZip's three conflict settings do

With EasyUnZip running, select the ZIP or RAR files in Explorer, press the configured hotkey (Alt+E by default), then select Choose a folder and pick the destination. On the next screen, under Conflicts, choose the policy for this job before extracting. The labels in the app are Overwrite, Skip and Rename.

Overwrite

Replaces colliding output files with the incoming ones. Use this only when replacement is intentional and you have a copy of anything important.

Skip

Does not extract an incoming file where that output file already exists. It can leave you with a mixture of old and new files.

Rename

Gives an incoming colliding file another name so both copies can remain. This handles ordinary same-path file conflicts; it does not compare contents or choose the correct version for you.

Rename is the initial default in EasyUnZip. Preferences can change, so read the current setting rather than relying on the default. The choice applies to the whole extraction job. It is not a backup or an undo operation.

EasyUnZip also cleans up Windows-incompatible names within the destination. Use a separate, empty folder if existing filenames must stay exactly as they are.

A conflict means the same output path

Imagine that your destination already contains docs\notes.txt. If the archive also contains docs\notes.txt, the extractor must decide what to do at that path. A file named images\notes.txt has a different path and is a separate case. Ordinary Windows folders also usually treat names that differ only by letter case as the same name, so capitalization is a poor way to separate copies.

Neither Skip nor Rename identifies duplicate content. Skip can omit a newly revised file. Rename can keep two identical files. For a website, software project or another folder with files that refer to one another by name, renamed copies can also leave those references pointing at the older file. Separate extraction folders are easier to review.

Keep a batch from mixing unrelated files

Two independent archives often contain the same paths, such as README.txt or images\logo.png. Sending both to one destination creates conflicts between the archives even when that destination was empty at the start.

EasyUnZip's Each folder routing puts each archive in a folder named after it, beside the archive. Check those names: assets.zip and assets.rar in the same parent folder both resolve to an assets folder. Extracting assets.zip again also targets that folder. For those cases, use Custom routing to choose distinct, empty destinations, or extract the archives separately.

See the batch extraction guide for the complete workflow. Whatever routing you use, read the conflict policy before starting a job that writes into an existing folder.

After a failed or interrupted extraction

A failed attempt may have written some files before it stopped. Retrying into the same folder with Skip can leave those earlier files in place. Retrying with Rename can produce more copies, without making it obvious which attempt produced each one.

Keep the failed output separate and retry into a fresh folder. Read the final report before using the result. If the archive itself will not open, follow the ZIP troubleshooting checklist before changing overwrite settings.
