مهما عيدت تسمية المجلد، ده مش هيغير الصورة الاصلية.

Not completely. It mixes Egyptian Arabic with more formal/standard Arabic.

• ده, مش, هيغير are clearly Egyptian.
• مهما, أعدت تسمية, المجلد, الصورة الأصلية are more formal or closer to MSA.

That kind of mixing is very common, especially in tech language. A more everyday Egyptian version would be:

مهما غيّرت اسم الفولدر، ده مش هيغيّر الصورة الأصلية.

مهما means something like:

• no matter...
• however much...
• regardless of how many times...

In this sentence, the most natural meaning is:

no matter how many times you rename the folder

So مهما introduces a concession: even if you do that repeatedly, the result still does not change.

In careful writing, it should be أعدت.

The expression is based on the verb أعاد = to do again / repeat, so:

• أعدت تسمية = you renamed
• literally: you repeated the naming of

People sometimes drop hamzas in casual typing, so you may see الاصلية instead of الأصلية, or اعدت instead of أعدت. But for learning, it is better to recognize the careful spelling:

مهما أعدت تسمية المجلد، ده مش هيغير الصورة الأصلية.

It is a formal Arabic way to say rename.

Breakdown:

• أعاد = to repeat / do again
• تسمية = naming

So أعاد تسمية الشيء literally means to re-do the naming of something, which is the formal equivalent of to rename something.

In more natural Egyptian speech, people often avoid this formal structure and say:

• غيّر اسم... = change the name of...

So instead of أعدت تسمية المجلد, many Egyptians would say:

غيّرت اسم المجلد
or even
غيّرت اسم الفولدر

In computer or file-system language, المجلد means folder or directory.

In Egyptian pronunciation, ج is usually pronounced like g, so المجلد is often pronounced roughly as:

el-mogallad

That said, in everyday tech talk, many speakers would simply say فولدر instead.

Here ده refers back to the whole previous idea: renaming the folder.

So it works like:

• that
• this
• doing that
• that action

In other words:

ده مش هيغير الصورة الأصلية
= That won’t change the original image

This is very common in Egyptian Arabic: ده can point to a whole situation, not just a single noun.

Because this is the normal Egyptian way to say won’t change.

Breakdown:

• مش = negation
• هـ in هيغير = future marker (will)
• يغير = change

So:

• هيغير = it will change
• مش هيغير = it will not change / it won’t change

This is a very common Egyptian pattern:

• مش هاروح = I won’t go
• مش هيحصل = It won’t happen
• مش هيغير = It won’t change

The verb هيغير has an implied هو subject, meaning he/it.

In this sentence, that it refers back to ده.

So the structure is basically:

• ده = that / this
• مش هيغير = won’t change

Together:

ده مش هيغير...
= That won’t change...

So even though English might say renaming the folder won’t change..., Egyptian naturally uses ده plus the verb.

Because in Arabic, adjectives usually come after the noun they describe.

So:

• الصورة = the image/picture
• الأصلية = original

Together:

الصورة الأصلية = the original image

Also, Arabic adjectives must match the noun in definiteness. Since الصورة is definite (the image), the adjective also has الـ:

• الصورة الأصلية
• not الصورة أصلية in this structure

A spelling note: in careful writing, الأصلية is more standard than الاصلية, though dropping the hamza is common in informal typing.

In unvowelized Arabic writing, أعدت can be ambiguous by itself.

Depending on pronunciation and context, it could correspond to:

• I renamed
• you renamed (masculine)
• you renamed (feminine)

Arabic script often leaves out short vowels, so context has to do a lot of work. In this sentence, the intended meaning is clearly you renamed, because of the translation/context.

This is one reason spoken Arabic often feels easier once you hear it: pronunciation helps remove ambiguity.

A more natural everyday Egyptian version would be:

مهما غيّرت اسم الفولدر، ده مش هيغيّر الصورة الأصلية.

Why this sounds more natural:

• غيّرت اسم is more conversational than أعدت تسمية
• الفولدر is very common in tech speech
• ده مش هيغيّر is already good Egyptian

So the original sentence is understandable, but it sounds somewhat mixed and semi-formal.

A rough pronunciation of the mixed-register sentence would be:

mahma aʿadt tasmiyet el-mogallad, da mish hayghayyar eṣ-ṣūra l-aṣliyya

A more natural Egyptian pronunciation of the more colloquial version would be closer to:

mahma ghayyart esm el-folder, da mish hayghayyar eṣ-ṣūra l-aṣliyya

You do not need to memorize the transliteration perfectly, but it helps to notice:

• ده = da
• مش = mish
• هيغير = hayghayyar
• ج in Egyptian is usually g, not j
